We open with a very unexpected sight -- Vince Leone behind bars.

In an erratically edited flashback, we learn that Vince punched a volunteer firefighter who had bonded with Sharon while she was away on the campaign fire.

He's released from jail the next day, but the marital troubles won't be resolved quite so easily.

Speaking of complex family dynamics, Bode is at camp reflecting on his own failures as a father when he finds out about his dad's brief imprisonment.

After an attempted peace accord between Vince and Sharon, a fire breaks out and the 42 and Three Rock teams are assisted by a drone pilot -- who happens to be Sharon's friend from the campaign fire, Liam.

Jake and Sharon respond to a call of stranded civilians and find a congregation of families who refuse to evacuate.

Eve and Manny clash over the exchange of power at Three Rock, but their fight is interrupted when Omar takes a bad fall off a cliff.

Gabriela treats one of the forest dwellers who's in danger of losing his eyesight.

When the evacuees' cars catch fire, Sharon is left with no choice but to cram them all inside her fire engine, with Jake and Gabi in a fire shield on the roof.

Her friend Liam tries to guide her through the flames, but it's Vince who steps in to save the day by saying all the right words.

Vince saves his marriage while helping to save his wife, and Sharon gives Liam the brush-off once she's back to civilization.

From there, Jake tells Eve that Bode is Genevieve's father, and Bode buries the hatchet with Gabriela.

He tells her that he has someone new in his life, but does not correct her when she assumes that he's referring to a romantic partner.
