It's 2 a.m. in a remote Scottish lodge.

You are asleep when a noise wakes you.

You stir, unsure why, and turn to your partner.

Then you hear it.

Glass. Crunching underfoot.

Your worst fears are about to be realized.

Someone is downstairs, intent on causing your family harm.

You will do whatever it takes to protect them.

But with only each other to rely on, can you escape?
