The show features eight couples who confront their past cheating issues, with notable intense confrontations involving Biggs Chris and Rebecca Gormley, who had a complicated history including accusations and breakups, as well as other couples like Kieran Hopkins and Amberley Elvines, and Shaun Peach and Tegan Connor, all navigating emotional and unresolved issues during the retreat in Mallorca.

Paul C. Brunson acts as a life coach and relationship expert who helps the eight couples work through their issues related to infidelity by facilitating conversations, guiding emotional processing, and encouraging decisions about whether to continue or end their relationships during the retreat.

Biggs Chris and Rebecca Gormley, former Love Island stars, dealt with difficulties stemming from their long-distance relationship during lockdown, accusations of Rebecca being a 'party girl' by Biggs, and complicated breakups including Biggs ending a subsequent relationship shortly before the birth of his son. These issues were central to their storyline on the show as they attempted to work through their past.

The show documents the couples' journeys to decide whether to give their relationships another try, with some couples managing to reconcile and others not. Specific outcomes vary by couple, but the series highlights both successful reconciliations and breakups after confronting infidelity issues.

The Mallorca retreat serves as a luxurious and isolated backdrop where the eight couples reunite to face their past mistakes and unresolved emotions. The setting intensifies the emotional atmosphere, providing a space for candid conversations, therapy sessions with Paul C. Brunson, and the pressure to make decisions about their futures together or apart.
