Celebrity guests are split into two teams to compete in various contests. One guest, known only to himself, is designated the "X-Man", and does his best to cause his team to lose the contests. At the end, all guests try to determine the X-Man's identity.

Male and female contestants compete for "each other" in romance games. For example guests have to dance in order to impress the person they are after. Contestants are artists, actors, models, comedians, and MCs of the South Korean entertainment industry.

A woman with a gift for lying is employed by a chaebol heir to act as his long-lost cousin. To keep up the charade for his family, the two must live under the same roof, but their growing attraction to each other poses a problem for pretending to be relatives.
