A brilliant, twisty sci-fi thriller is now streaming at home for free

'A satisfying mind-twister, with an unexpectedly poignant pay-off.'

Written and directed by cult filmmaker Christopher Smith (Creep, Severance), it stars an excellent Mellisa George (30 Days of Night) as Jess, a stressed-out single mother who goes on a boating trip with several friends (including Liam Hemsworth and Michael Dorman).

When a sudden storm capsizes their vessel, the group boards a derelict ocean liner. There, however, they become convinced that someone is stalking them.
