Never turn your back on a friend.

Jade, Stef and Zoe are hiking Washington's Bones Hollow Trail, braving cougars, snakes and the storms that roll in without warning. The friends' paranoia isn't helped by listening to a true crime podcast about the serial killer whose hunting ground they're hiking through.

Then when Stef twists her ankle - badly - there's no one to hear them scream for help. The only sign of life for miles is a cabin that looks straight out of a horror movie, with an owner who's a little too eager to invite them in.

The friends must soon find a way to survive as things spiral out of control. After all, who can you trust when your back's against the wall?

But unfortunately for them, the only thing more twisted than this nightmare is their friendship...
