In this show, Keller plays a mutant with the ability to switch bodies with another person she touches. Her mind transfers to their body and vice versa. In the episode, Keller’s character Syd makes contact with another male character and after the switch, the man (now in her body) collapses to the ground unconscious. After this guards rush in just as “Syd” is waking up, but he/she is swiftly kicked in the face by the real Syd in the man’s body, knocking her/him out again instantly. Hope that wasn’t as confusing as it sounds when I’m reading it back.
