Created and written by Ryan J. Brown, the comedy horror - with an element of slasher - takes place aboard The Sacramentum cruise ship. 

New recruit 20-year-old Jamie (Oscar Kennedy, Ladhood) has joined the ship to try and infiltrate the 3,000 strong crew in a tense race to find his missing sister, who was working on the same ship during a previous tour but vanished mid charter. 

As Jamie learns the realities of cruise life, he discovers the different tribes within the staff, from the theatre kids, to the mafias, to the low paid workers. 

With staff overworked and underpaid, life below deck is a hedonistic mix of partying and excess. However, unbeknownst to the crew, bloodthirsty and gruesome murders are occurring on board, forcing Jamie to turn detective and uncover the sinister truth. 

The rest of the cast includes Thaddea Graham (The Irregulars) as Vivian, Jack Rowan (Noughts + Crosses) as Danny, Harriet Webb (I May Destroy You) as Karen and Jodie Tyack (The Window) as Pippa.

The six-part series is currently filming in Northern Ireland and will air later in 2022.
