Everything is a clue.
Bonnie arrives on a remote sea fort off the coast of England to take part in a mysterious reality TV show. Competing against seven strangers, she must solve a series of puzzles to win the prize money, but this is no game - and the consequences of failure are deadly.
No one leaves.

When the first contestant is found dead, Bonnie begins to understand the dark truth at the heart of this twisted competition: there's a killer inside the fort, and anyone could be next.
If Bonnie wants to escape, she needs to win...
