In the trailer for GTA 6, the first shot of the main female character establishes the context that she is in a prison. In GTA 5, the first mission(Prologue, which acts as a tutorial) happens in North Yankton Ludendorff, where Michael, Trevor and Brad rob a cash storage facility. Will the first mission of GTA 6 take place in a prison?

Question will resolve YES if the prologue mission(the mission the game first drops you in) takes place in a prison. Cutscenes do not count, there has to be actual gameplay inside the prison.

Question will resolve NO if the prologue mission doesn't take place in a prison.
