Channel 5 is preparing to launch a suspenseful new thriller that explores the consequences of a break-in at the home of an affluent couple.
Sam and Rebecca are high-flying media professionals who live in a luxurious house by the coast, but both are harbouring dark secrets that could tear their seemingly perfect life apart.
The pressure begins to rise after two local youths attempt to burgle their fancy abode, but only one leaves the premises alive and the couple are reluctant to divulge what happened to the police.
Over the course of this four-part event series, we'll see whether this power couple can pull themselves out of the mess they've made or if this is the spark that will detonate the world they've built once and for all.
