Viewers meet the players and learn the concept of the game. The players begin forming coalitions in the hope of making further in the game and learning more about who is the mole. The players all take part in a sky-diving challenge. The players' banking skills are tested in an attempt to earn money for the pot.

A bullfighting game confuses the players, but they are still able to earn money for the pot. Some players come face-to-face with their dirty laundry, literally, while others are asked to unpleasant tasks. One player is asked to face all four, but the stakes in this case are higher: more money and an exemption. Fortunately, the negative results are only temporary, at least in some cases.

A sniper game provides a player with a choice between money or an exemption. A losing streak gets the players down, but a school-style challenge gives them an opportunity for big money. Some prove rather easy, while others are too much of a challenge to handle. The game becomes more complicated in a twist in which correct answers lose money for a new group answering the questions. One player claims to have psychic visions about the night's execution, but ends up being executed instead.

The players are divided into "Stupid," "Resourceful" and "Smart" teams for various games. Transportation dilemmas hinder the progress of all of the players. The players then take part in a game that tests how well their loved ones know them. Successful answers earn money for the pot and a chance for the players to see their loved ones, while incorrect answers lead to heartbreak, but only for a short time.

The players compete in a game described as a variation of "capture the flag." The game raises many suspicions as to who could be the mole and causes some finger-pointing. In Spain, the players attempt to decipher Spanish clues to search for books. Alleged verbal abuse causes one player to despair and they are executed.

The players divide into "arty" and "counting" groups and then participate in games in which they herd sheep or create a piece art designed to fool a critic. The sheep-herding group is given a choice of three dogs, with only one trained to herd sheep. They can earn $20,000 for herding them, and an additional $10,000 for counting them. What they don't know is that they've already been told the number of sheep. The players then are asked to challenging tasks, such as facing knife-throwing and fire-walking. The tasks are on a tiered-structure, with varying results worth exemptions and/or cash. The participating players are blindfolded, while another has to convince them to complete their tasks. This player is the only one who knows the truth about their tasks: that they only think they're doing something potentially dangerous.

Now that only three players are left, the remaining players take part in some final games. One mean game forces the players to answer revealing questions about each other, in the hopes of using information earned this way to find each other and earn money for the pot. In the final game, the players are locked in hotel rooms and try to decipher clues working together in order to escape and earn a large chunk of money to the pot. They fail, leading the two actual players to wonder if it was the mole's work.

The final episode reveals the mole and the winner. Montages reveal moley action, previously-unknown alliances and more. Recaps offer a look back at some of the best moments of the first season if the show. The viewers are informed that hidden clues to the mole's identity were placed in episodes throughout the series and these clues are revealed.
