A bold new social experiment exploring whether relationships can thrive without monogamy. Cameras follow a group of currently monogamous couples as they explore for the first time whether they would be happier in an open relationship. In this first episode, Welsh sweethearts Mady and Nathan are interested in bringing another woman into their relationship, a process that begins by having a threesome.
