The Mole - Season 2 - Eps 4: The Fourth Betrayal
The players have their memory tested in a game in which they try to crack a safe. The players receive a secret telegram that contains a vital, secret and unpicked-up-on clue. A secret game tests the moral integrity of the players and they are then separated into "dumb" and "smart" groups as brainteasers test whether the players in this edition are worthy of the "MENSA" tag the show has earned. One player's rule-breaking actions lead to a fine being levied on the entire group.

Players working as a team complete a series of difficult physical and psychological tests, each worth a set amount of money. One of the players, however, is a "Mole" or saboteur, whose goal is to foil the efforts of the other players without revealing his or her identity. At the end of each episode, the group is given a quiz on The Mole's identity. The player who knows the least information about The Mole is then immediately sent home. In the final episode, The Mole is revealed and the one remaining player wins the jackpot, up to $1,000,000.
