Danko is sent to Chicago where he teams up with vocal, wisecracking, plainclothes detective Art Ridzik (John Belushi) in order to track down Victor to extradite him. After he was captured and escorted by Danko and Ridzik, though, Viktor escaped when he was assisted by the Cleanheads, who were dressed like policemen. Ridzick's partner was killed in the mêlée.
Thus the only plot of this action-thriller is to capture Viktor; there is neither mystery nor intrigue. There are, however, the obligatory shoot-outs and chase scenes. Note that neither Ridzick nor Danko believes in the Miranda Act. The ending involves a bus chase through the streets of Chicago at night, followed by a duel. This is the first movie in which an American director was allowed to film on location in Red Square. It was also filmed in Budapest and in Chicago.
