This feature-length story about the heist of $10 million in Nazi diamonds primarily rides on star Tom Selleck's popularity as TV's Magnum, P.I., (a 1980s show), since the plot turnarounds, slighted character development, and stock situations are not that engaging on their own. The setting is 1934 and Nick Lassiter (Selleck) has been strong-armed by the Yank and Brit governments into stealing the diamonds from a German agent (Lauren Hutton) -- if he can track the gems to their hiding place. Along the way, he travels through London of the 1930s -- marketplaces, warehouses, and watering holes that lend an atmosphere to his search. His lady love Sara (Jane Seymour) more or less stands around to lend support while the suavely suited-up Lassiter battles a crooked cop (Bob Hoskins), his real arch enemy. ~ Eleanor Mannikka, Rovi
