David Tennant and Emily Watson are teaming up again, five years after starring together in The Politician's Husband.

Deadline reports they're playing a couple once again, this time on the Greek island of Crete, in Quicksand, a film described as a "taut psycho-thriller." Here's what we know:

Quicksand follows British couple Dan (Tennant) and Sarah (Watson) living out their dream in the Mediterranean. But their paradise is shattered when their visiting son is murdered by a local youth. Dan is offered a chance at revenge by a dangerous stranger who won't take no for an answer, and it emerges that the price of revenge is... another murder.

It has a slight The Twilight Zone vibe if you ask us, or Black Mirror for a more contemporary reference. It also sounds more in line with the horror-thriller Bad Samaritan David starred in this year than his more light-hearted recent work.

Quicksand is due to start filming in April, with director Mark Brozel (Humans, Troy: Fall of a City) at the helm. Expect it to hit theaters later in 2019.
