Based on an overseas format, Touchdown reality series Captive was based on a simple idea: five strangers move into a penthouse apartment and as long as they want to stay in the competition, they cannot leave. Luckily there is motivation, in the form of prizes worth up to $40,000. Contestants are quizzed not only on trivia, but on their fellow housemates. At the end of each episode, whoever fared worst in the quiz is evicted from the house empty-handed, and replaced. Alliances are formed and new friendships broken as they attempt to get to know each other.
