A Game of Lies

They say the camera never lies.
But on this show, you can't trust anything you see.

Seven reality show contestants arrive in the Welsh mountains to compete for a life-changing prize, not realising what they're truly signing up for.

Each stranger has a secret - and the show will force them to expose one another live on air.

It's not long before things take an even darker turn, and Detective Ffion Morgan is summoned to untangle the truth behind the scenes.

And when a murderer strikes, every one of Ffion's suspects has an alibi . . . and a secret worth killing for.
