The series stars Jill Halfpenny (Liar) as Jodie, a mother still recovering from the loss of her son who went missing eight years ago.

When she encounters Daniel (Cody Molko), she is convinced he is her son. But her fixation threatens to collapse the life she’s painstakingly rebuilt, as it leads her down a dangerous and morally dubious path.

In Jodie’s way stands Daniel’s impassive and protective father, Mark (Rupert-Penry-Jones).

Jodie has a strained relationship with her mother Lynn (Deborah Findlay), which means her only sibling Jason (Jonas Armstrong) is also her only shoulder to lean on. Meanwhile, Jason is on the cusp of a huge promotion at his law firm.

“We are delighted to be working with the hugely talented Jill Halfpenny, Jonas Armstrong and Rupert Penry Jones on The Drowning, which is being led by the brilliant director, Carolina Giametta," said Unstoppable Film & Television’s Noel Clarke and Jason Maza, who are producing the series.

"Working with Carolina and our wonderful writer, Tim Dynevor, the creative process has been a joy."

The Drowning will be filmed in Dublin and the four-part series will air on Channel 5 later this year.
