A reality show that follows eight British couples as their relationships are tested through a series of tasks and eventful surprises. Set in the idyllic surroundings of a Mexican beach resort, the pairings are tactically split up and must instead spend some quality time with the partners of their fellow contestants. After a few action-packed days filled with drama and some honest conversations, the eight original couples are reunited to see if they wish to prolong their relationship, or to call it off and go their separate ways.
