The film that launched Kevin Costner's career as a leading actor and a super smart, cat & mouse thriller it is too. He plays US Navy Intelligence officer Tom Farrell who is appointed as the intel' liaison for Senator Brice (Gene Hackman), the Secretary of Defence. He gets the job through a friendship with Scott Pritchard (Will Patton), Brice's aide-de-camp and who is fiercely loyal to Brice. The trouble is Tom begins a passionate relationship with Susan (Sean Young) who is also Brice's mistress. When she refuses to tell Brice who she is seeing he flies into a rage and kills her. To protect his boss Pritchard begins a cover-up investigation claiming she was murdered by a Russian spy and he puts Tom in charge and he quickly suspects the spy story is false and that Brice is the killer. This is a twist and turn plot with espionage aspects and some fantastic chase sequences. It's a really good gem of a film with a surprise ending and even if you've seen this and know the ending it's definitely worth checking out again. If you've not seen it then it's a real treat.
