Basically there are 2 people and they are each given some type of shoplifting mission (ex. car from car wash, 6 dildos & 6 dvds, suit, everything off the table at a restaurant). Obviously the goal is not getting caught.
EDIT: If you were caught you would get in the same trouble as you would if it weren't part of the game show. If you weren't caught you'd be able to keep the items.
