The teams are put to the test for the first time with a tempting food competition. Each contestant will need to decide whether it is worth it to participate when they are put in a room full of unhealthy food. They have four minutes to consume or not consume the most calories and the winner will receive a three-pound pass that will be used to their advantage at this week's weigh-in. In the physical challenge, contestants will participate in three different 100-meter heats against the yellow team formed by three kids. Host Alison Sweeney informs them that the winning team will receive a phone call home, making the stakes this week even higher. After the weigh-in one of the teams will have to send someone home.

This week Alison surprises the three teams with news of an exotic getaway, but they quickly discover their vacation will be more work than play. The contestants are faced with temptations they never had to face back on campus, and later square off in a wild challenge unlike any they've faced before. Then back on the Biggest Loser campus, contestants who lose the weigh-in try to forge alliances before making the difficult decision of who to send home.
