After their friend Rob (Paul Reid) is killed during a robbery, Hutch (Robert James-Collier), Luke (Rafe Spall), Phil (Arsher Ali) and Dom (Sam Troughton) go to Sweden together to go on the hiking trip that Rob suggested just before he died. Despite not being very experienced hikers, everything goes well until Dom falls and twists his ankle. They decide to deviate from the original plan and go through the forest instead of around it. But there is something in the forest. Something that is hunting them.
The Ritual starts off well enough when establishing its characters and their situation. But once it would have been time to really dig in to that, it turns to scariness instead and loses its grip on the story and the audience watching.
