It takes place on an isolated island lighthouse far away from the mainland and prone to frequent storms. A bizarre murder countdown begins - the lighthouse is about to be completely isolated from the world due to a storm (physical countdown), and serial murders occur in the lighthouse (death countdown). When each victim dies, they are left with a weird, handmade hourglass or clock that points to the next victim (or time?).
