A headstrong airline tycoon pays the ransom for his abducted son, despite the pleas of his wife and FBI agents, then must gamble on the consequences of attempting to turn the tables on the kidnapper, setting up a gut-wrenching confrontation between the anguished father and the increasingly desperate criminals. This tightly conceived nail-biter, with head-spinning plot twists, is another fine effort from the director of "Apollo 13."
