Ella-Rae Smith from Netflix's The Stranger and Matthew Daddario from Shadowhunters are teaming up to star in a new thriller called Into The Deep, Deadline has reported.

The film is now shooting in Cornwall, and follows a young woman named Jess, played by Smith, who meets a stranger promising to take her away from the small coastal town she lives in. The couple holiday on his yacht, but mistrust and violence soon follow, making Smith's character fearful of the person she's with.

Kate Cox will be making her debut as director while David Beton, who wrote The Banishing, will be writing the screenplay.
