Snatch.

When a dizzying robbery takes place in the Orthodox Jewish diamond district, a flawless 86-carat gem, the size of an infant"s fist, is lifted in the snatch. Taking it to London, the diamond"s thief and courier, Franky Four Fingers arrives in the city as a stopover en route to New York to deliver the huge diamond to his bigwig crime boss, Avi. But because Franky can"t resist temptation and London is a town with its share of illegal trade, a small crowd of miscreants and malefactors eventually ends up chasing each other and the whereabouts of the diamond. These include: Doug the Head, a jeweler who pretends he"s Jewish because it"s good for business; Boris the Blade, a Russian gangster with a deserved reputation for being impossible to kill; Bullet Tooth Tony, a legendary hard guy and Brick Top, perhaps the scariest of the lot.
