Ruby and Roarke meet at the dock. Roarke has plans for a special dinner with Javier.

Nora (Maxwell Reid), Judy (Whitfield), and Marsha Butler) are friends from Minnesota. They’ve been good friends for over fifty years. They are on the Island for a fourth friend who went missing.

While Ruby gets them settled, Javier lets Elena know that he’s had to change his plans in order to take Helene to the mainland for a shopping trip. Ruby sounds a bit envious of the trip.

The friends tell Elena and Ruby about their friend, Rosemarie. With her, they were the Fearsome Foursome back in the 80s. Their fantasy is to learn what happened to her.

Their fantasy begins by transporting them to 1980s Miami.

They change into appropriate clothes for the era, find their car, and discover a map with a marked destination waiting for them. They embark on their adventure.

Ruby’s sitting alone when Elena finds her and Ruby asks if she would be able to leave the Island the way Helene does. Elena confirms her understanding that if she left the Island, she’d die the way she would’ve if she’d left with Mel after their trip there.

The trio arrive at the address on the map and spot a condo with gardenias planted out front. Nora is determined to knock on the door and find Rosemarie. As they leave the car, a man in a pink leisure suit, reading a newspaper, watches them go.

When they arrive at the condo’s door, it’s been broken into. They peek inside and find what looks like blood and a broken vase. They search the condo for clues.

Roarke brings Ruby to the ladies’ fantasy portal. She explains that the guests’ fantasies provide a loophole to not being able to leave the Island. She gives Ruby some money and a room key and tells her to take a little holiday in 1980s Miami.

In the condo, the women discover Rosemarie had been running a real estate scam. Marsha notices the man in pink walking around their car out front. She also notices that he’s carrying a gun. When she tries to warn the others, they’ve redialed Rosemarie’s phone and discovered that she’d been in touch with Marsha back in the 80s.

She distracts them with the danger of the man in pink. They try to sneak past him in the lobby but he spots them and chases them. They speed away in the car but he pursues them.

Ruby joins a crowd of rave party goers.

When they’re able to pull to the side of the road, Nora and Judy demand Marsha explain the call. She does, but they’re dissatisfied with the explanation. Nora accuses Marsha of being bossy and unable to enforce boundaries with her grown children who still live with her and Judy of being ineffectual. Judy pushes back, telling Nora her life is boring.

Segundo finds Elena drinking wine by herself. He points out that she’s changing and letting people in, like Javier and Ruby. With both of them away, she’s feeling lonely for the first time in a while.

The women bicker until they find themselves at Ruby’s dance party. Ruby tries to smooth things over for them. She suddenly realizes something about being in Miami in 1985 and leaves, extorting a promise from the trio that they’ll stick together.

They immediately become separate when a crowd of people pushes past them to the dance floor. They each spot Rosemarie in the crowd and follow her through a door. Individually, they enter her kitchen. She offers each of them pastries – the ensaimadas she’s always loved, – commenting that she’s been waiting.

Judy demands to know where Rosemarie has been and hugs her. Judy accuses her of abandoning her. Rosemarie hands her a plate, stating that she understands that Judy is angry but it’s not her she’s angry at. When Judy asks what the plate is for, Rosemarie smashes one and tells her she’s going to need it.

Marsha apologizes for not trying to help when Rosemarie phoned her. Rosemarie reassures her that she has nothing to feel guilty about whether it’s about Rosemarie or her kids. Rosemarie makes some coffee.

Nora tells Rosemarie that she doesn’t blame her for living the criminal life. Nora feels boring compared to Rosemarie. Rosemarie asks if she’s just bored. Nora confides that Rosemarie’s disappearance was the most exciting event in her life.

In Judy’s scene, Rosemarie gives her plates one at a time to smash as she works through her anger and grief at her husband’s death.

In Marsha’s scene, Rosemarie points out that despite being divorced over twenty years, she still feels guilty towards her kids for leaving their father. Rosemarie reassures her that she made the right choice and needs to let go of her guilt and start setting boundaries for her kids.

Nora confides that she hates her husband’s dream retirement, playing golf all day.

In the aftermath of the dish smashing, Judy has a pastry and recalls that Rosemarie had broken up with a man named Bill just before she moved to Minnesota. Rosemarie says he wasn’t one of the good ones.

Rosemarie reminds Nora that she introduced Rosemarie to the ensaimada pastries she loves so much.

Marsha recalls that Rosemarie found the best Filipino bakery in Minnesota. Rosemarie comments that she went so often, she made friends with the baker.

Rosemarie says it’s time for her to go, that “he” is looking for her.

As the three women follow her out of her kitchen, they all find themselves back in their hotel suite.

Elena greets them and unpacks some of what they’ve learned about themselves and Rosemarie.

Nora organizes them to create an evidence board to solve the Rosemarie mystery.

Ruby’s raver friend asks who she’s waiting for. She tells him about Isla, and then lets him know that there’s going to be a surprise appearance by Prince, playing a private set in the tiny room after his stadium concert. Prince walks in just then.

As Nora’s returning to the room with supplies, the man in pink yells at her. She runs into their room. He follows, reaching into his coat for something. Judy clocks him over the head with a bottle. He falls down but isn’t knocked out. He pulls out FBI ID.

He’s after Rosemarie’s ex, Bill. Nora insists that they cut her a deal so she can help put Bill away and stop running. He points out that Rosemarie’s still running so he can’t cut her a deal. Nora has an idea where they can find her.

Segundo checks in with Elena to see how Ruby’s holiday went. Elena confides that she and Javier have been growing apart because she’s been giving him space to get to know Helene. Segundo advises that she be honest with Javier about her feelings.

Elena picks up Ruby in the morning. Ruby is charged up from her night in Miami and eager to get home. She is determined to see Isla.

The trio finds the best ensaimada baker in Miami. They reassure her that they are just trying to help Rosemarie too why she unconvincingly denies seeing her. They give her an envelope to pass onto Rosemarie when she sees her again. She agrees.

The women are transported back to the Island and Elena. They protest that they don’t know how things turned out for Rosemarie. The real Rosemarie, now also in her seventies, appears and tells them that she got the message they left for her.

Ruby walks the beach looking for Isla, calling her name. Isla appears, impressed by how vibrant Ruby looks. Ruby kisses her. She tells Isla she experienced real human connectedness magic in Miami and wants more of that to sustain her vibrancy if she’s going to spend the rest of her life on Fantasy Island. They kiss some more.

The four friends sit down to catch up. Elena informs them they have lots of time. They are all invited to spend the rest of the week on the Island. Rosemarie explains she changed her name after testifying at Bill’s trial, became a physical therapist, got married, and had kids (and grandkids).

Marsha invites her to come stay with her in Minnesota where she’ll have lots of room because she’s kicking her kids out. Nora informs them that she’s starting a murder mystery dinner party business. Judy invites them all to a memorial service she’s planning for Hank.

Elena’s arranged a tour of the Island for the women, guided by Segundo, who has been missing spending time with people his own age.

Elena finds Javier waiting for her when she returns to her room. She tells him she missed him and asks him if it’s okay for her to start to get to know Helene as well. He’s happy she wants to.
