The series premiered on January 10, 2001, and it concluded with its third season on September 29, 2003. It depicted four unmarried couples who traveled to a tropical island to have their fidelity tested. The couples were separated from one another for two weeks, in which they were required to commingle with a group of single members of the opposite sex whose purpose was to persuade the couples to have an affair. The series drew intense backlash due to its controversial premise; however, it averaged high ratings over the course of its first season. A revamped version of the show, once again hosted by Mark L. Walberg, premiered on the USA Network on January 15, 2019.
