Mulder believes in the existence of aliens and the paranormal while Scully, a skeptic, is assigned to make scientific analyses of Mulder's discoveries that debunk Mulder's work and thus return him to mainstream cases.

Needing to get his yah-yah's, Mulder enters the game to fight the woman, but Scully must step in to save him.
