Firecracker Films’ bold social experiment for Channel 4, devised by Chief Creative Officer Jes Wilkins. Previously monogamous couples arrive at a luxury retreat to explore whether opening up their relationships can strengthen their bond, guided by sex therapists and relationship coaches. Channel 4’s biggest new unscripted 10pm series launch since 2017, now commissioned for a third series through the broadcaster’s Global Format Fund, with international format interest from Australia, the US and across Europe.
