Harvey Keitel plays John Harris, an American drug enforcement officer who is asked by London police to help them in cracking an organized drug ring. The syndicate is run by a ruthless young American who turns disaffected young Britons into hardened criminals. The gang has gunned down a well-known mobster and supplies cheap heroin to dance clubs all over London. Harris hooks up with British police officer Edward Foster (
Iain Glen). They discover that the drug ring is just a small part of a huge international mob -- and that a young man whose own father has worked for the American-run mob all his life is the key to cracking the ring. ~ Michael Betzold, All Movie Guide
