Hide and Seek (DVD)

A rather naive Cambridge astrophysicist who visits an old Russian pal (a former chess champion) who's playing exhibition matches against many different players at once. After the games, the Russian accidentally(?) leaves his chess box with Carmichael, who finds a small fortune in bills inside. In his attempts to find his Russian pal, he finds himself falling deeper into an espionage plot that leads him into a boatload of danger.
