After being convicted for the murder of his wife Tara, David Collins (Lee Ingleby, The A Word) has spent the last seven years in prison. Despised by his family and friends, he's lost everything, including his two children who now live with his wife's sister Alice (Hemione Norris, Cold Feet) and her husband Rob (Adrian Rawlins, Dickensian). Only David's faithful brother Phil (Daniel Ryan, Mount Pleasant) believes in his innocence - so much so he has sacrificed his own career to prove it.
David's situation couldn't be more desperate…until he's shockingly released from prison on a technicality and begins trying to pick up the pieces of his shattered life.
Upon his release, D.I. Cathy Hudson (Angel Coulby, The Tunnel) is assigned to reinvestigate the case and quickly begins to uncover dark secrets about David and his family. Will the tenacious investigator discover what really happened the night Tara was murdered or does the newly released David have something to fear?
