Mariner decides to recode the program to create her own role-playing therapy program to deal with her issues with Freeman. It plays as a movie called Crisis Point: The Rise of Vindicta.
The movie begins at Kabba Lake Command Retreat where Freeman leads her senior crew on hydroscoots as they celebrate her birthday. Boimler tries to question Freeman but she is recalled to her mission.

Vindicta arrives at the bridge and takes out all the security in order to confront Freeman. After a back-and-forth, Vindicta detonates her own ship, damaging the Cerritos and sending it crashing through the planet's atmosphere. It crash lands and the disc detaches and rolls a great distance before becoming lodged on a rocky outcropping.

In the crew lounge, Mariner chats with Rutherford and apologizes to Tendi and then they all go to look at the warp core.
On the way, they run into Freeman and Mariner apologizes which confuses Freeman who goes to Dr. Miglibo who just frustrates her.
Boimler jumps back into the holodeck program and discovers that Freeman is Mariner's mother. The holodeck Freeman states that the secret was so sacred that she'd probably kick out anyone who stumbled upon the knowledge. This freaks out Boimler so much that he flunks his evaluation.
In a holodeck stinger scene, Vindicta arises from a Genesis pod seeking revenge only to be shot dead by DaVinci.
