Little Caprice and Marcello Bravo are an open swinger couple who have been together for over 13 years and are exploring new experiences together. While jogging, Caprice meets Matthew, who turns out to be her husband's running partner - a conversation quickly develops into a flirtatious exchange in which Caprice reveals the nature of their relationship. Matthew is both intrigued and unsettled, which leads to a secret meeting that he tries to hide from his fiancée Eve.
However, when Eve finds out about the meeting through a note, she is shocked – but instead of admitting defeat, she seeks a confrontation that ultimately culminates in an explosive meeting between the two couples.
