A group of people participate in a challenge where they have to retrieve "dive sticks" with different amounts of money on them. The person with the most money at the end gets to keep the money, but with a twist: they have to spend it on someone else. The group is given a time limit of one hour to shop for the person they have chosen, but they must keep their choice a secret. If they fail to guess who bought them a present correctly, they will have to be that person's "slave" for the day. The group members go shopping, trying to find the perfect gifts for their secret person, and eventually, they return to exchange gifts and try to guess who bought what. The person who correctly guesses who bought their gift is exempt from being a "slave," while the others have to serve the person who bought them a gift.
