Booby Trap, TNG 3
1/2
A classic race-against-the-clock episode as the Enterprise falls into an old trap for a long forgotten war. LaForge can only solve the riddle by monkeying about in the Holodeck and (naturally) falling in love. When he kisses his holo-girlfriend we finally see the first inkling of what we all know is the real reason to have a Holodeck on a multi-year deep space mission.
