A love triangle is already an explosive situation without the added complication of an unexploded bomb. But the Luftwaffe's 1944 legacy of a large bomb exposes a burgeoning romance and throws together the three people in the love match. Trapped in a collapsed hole with a ticking WW2 bomb for company, the love cheat's hope of escape is in the hands of the man he is cuckolding. Will the frantic race against time succeed? Or will the husband take revenge? The stark outcome can only be a blast from the past or UNEXPLODED LOVE?
