Beyond Paradise Christmas Special | Preview (BBC One)

In Shipton Abbott, the guest arrivals docking into the Devon seaside town for the holidays include Adrian Edmondson (Alien: Earth), James Lance (Ted Lasso) and Jonny Weldon (One Day).

They’ll be joining Kris Marshall (DI Humphrey Goodman), Sally Bretton (Martha Lloyd), Zahra Ahmadi (DS Esther Williams), Dylan Llewellyn (PC Kelby Hartford), Barbara Flynn (Anne Lloyd), Felicity Montagu (Margo Martins), Jamie Bamber (Archie Hughes) and Melina Sinadinou (Zoe Williams) to serve up another helping of yuletide cheer.

An elderly man living with dementia turns up on the police station steps, clutching only a photograph of Humphrey. He's searching for his sister, Louise, and believes that Humphrey is his last hope. But with precious few clues to her whereabouts, the team must work against the clock to unravel the mysteries of his past.

Just as they dive into the search, the station is rocked by another call. There’s been a break-in at a local wine bar, where the team celebrated their Christmas party just hours before.

On top of this, Kelby is called to an unusual emergency: a man hopelessly trapped inside a snowman suit after his head was glued on as a prank. As the clock ticks down, could the snowman hold a vital clue to solving another festive mystery?

With an influx of unexpected visitors, a slew of holiday crimes to crack and a heartwarming reunion on the line, can the team juggle it all and still be ready for a life-changing reveal?

Beyond Paradise Christmas Special airs Sunday 21st December on BBC One.
