In this suspenseful thriller, David Parker (Bryan Brown) is a married businessman with three children, a mistress in Germany, and a brother dealing drugs -- a combination of relationships that will eventually prove fatal to several people. After David leaves his London home and family behind for a short business-trip to Munich, he is held captive for more than a week by ten men and one woman, their identities disguised by masks. David starts to suspect Jillian, his mistress (Hannelore Elsner) is involved because when he goes to the police with his story once he is released, he discovers he was never reported missing. Why did Jillian remain silent about his disappearance for eleven days? And there were no ransom demands. After awhile the police inspector assigned to David's case (Kurt Raab) and David's wife (Cherie Lunghi) begin to doubt the kidnapping itself. At that point, David launches into a full-scale investigation on his own that sets into motion a series of killings and a strong suspicion of drug-world involvement.
