Plot Synopsis

When a young woman's body is found in a river -- with evidence that she had been held prisoner -- the investigation leads DI Cadi John to a string of disappearances in a remote yet striking corner of Wales. Cadi and her colleague DS Owen Vaughan identify the body as Mali Pryce, a troubled girl who disappeared years ago. The detectives interview Mali's friend Sara, who points them to Mali's dangerous ex-boyfriend. The entire eight-episode first season of HIDDEN made its U.S. debut on Acorn TV.

In Season 2, newly promoted DCI Cadi John and DS Owen Vaughan investigate the brutal murder of a former schoolteacher. Nine months after the the end of Season 1, Cadi and Owen head out on their next major assignment when an anonymous phone call is received at the police station about a local retired chemistry teacher, Geraint Ellis, who was found murdered in his bathtub. Rumors about the victim -- and the reasons for his sudden and unexpected retirement -- soon emerge. While Cadi and Vaughan have a new case on their hands, three teenagers -- Mia Owen, Connor Pritchard, and Lee Williams -- have blood on theirs. As their lives -- and the investigation -- unravel, they soon find out there is nowhere to hide. Was Ellis targeted for previous sins, or an innocent man unjustly singled out by disaffected teenagers? The investigation draws Cadi and Owen deeper into the troubled lives of these young mysterious characters -- as they uncover a world of lies, revenge, cruelty and neglect. When not hotly pursuing new leads and navigating endless twists over the course of this complicated investigation, Cadi and Owen deal with major life events: Cadi is grieving over the recent death of her ex-police detective father and feels guilt about disproving an important case of his before his passing, while lending much-needed emotional support to her family. Meanwhile, Owen adjusts to caring for his newborn baby girl. All six episodes of HIDDEN's second season made their U.S. debut on Monday, June 15, 2020 on Acorn TV.
