The Presidio

“He didn't want to share the murder investigation. There's no way he's going to share his daughter.”

Jay Austin (Mark Harmon) left the military police over a disagreement about a drunk driver, and he's now a civilian detective in San Francisco. A string of murders crossing jurisdictions puts him back beside Lt. Col. Alan Caldwell (Sean Connery), his old commanding officer. Peter Hyams sets the two men on the same case, with Caldwell's daughter Donna (Meg Ryan) sitting between them, since Austin is dating her.
