Summer, 1940. The Battle of Britain is lost. Operation Sea Lion is now in full effect. Germany invades the coast of Britain, only several fortresses are left standing in the defence against tyranny. Amongst the chaos, two enemy soldiers find themselves trapped in one such fortress together.

Paul, a loner, is worn down by years of quiet suffering. Burdened by loss, isolation, and a growing sense of worthlessness, he wanders through life like a ghost, unseen and unanchored. Intending to end it all, a stranger appears - Marcus. Could this encounter be a turning point in Paul's life, or is it too late?
