The Protector (1999)

A former mercenary devotes his life to protecting the innocent in The Protector (1999). Ever since Gabriel (Ed Marinaro)'s wife was killed while he was away on a mission, he has devoted himself to protecting anyone whose life may be in danger. His newest client is Alex Johnson (Kate Rodger), a woman whose gangster boyfriend goes ballistic at the sight of her anywhere near another man. After he kills one of their co-workers after spying them in the office together, Gabriel offers to help Alex break up with him...the hard way. That may seem a bit extreme, but if your girlfriend had a body like Kate's (which she shows off in a full-frontal open-robe reveal), you'd be jealous, too.
