Jacinta Quirke and Maxine O'Malley, a.k.a. Jax and Max, need a plan, fast. They've just heard rumours that they are about to lose their jobs at advertising agency ACJ in Dublin. Could they make it in the (supposedly) more lucrative world of TV? Their proposal: a documentary on fidelity. Is long-term monogamy a sham as cynical Max believes? Or will Jax, the hopeless romantic, prove her wrong. Putting a variety of couples into the hot seat, they get the cameras rolling. But when they turn on each other's love-lives, the trouble really starts... Friendship, passion and fidelity - nothing's ever simple when it comes to love.
