When Chris' family's restaurant is tagged after Sam's Black Lives Matter march, a mysterious question mark-faced figure takes the credit and threatens more. The search to unmask their identity leads the group to one of their own.

After an unlikely confession, Nira vows to find the truth. But the group’s hunt for clues only makes the suspect look guiltier, until Chris finds new evidence.

After making contact with Question Mark Face, the friends set up a sting to catch them. What they don’t realize is that their target is already one step ahead.
