Renegades

Kiefer Sutherland is an undercover cop trying to take down a dirty cop, which somehow involves him in a museum robbery; jewelry and the Lakota's Sacred Lance are taken, and Lou Diamond Phillips' brother is killing trying to defend it. Sutherland is wounded, so Phillips gets him healed and then proceeds to help him track down the dirty cop, despite Sutherland being one of those mavericks who only work alone, etc. You know the trope; it's usually accompanied by "this time it's personal" because otherwise he'd be in a diabetic coma from all the glazed doughnuts.

Phillips spends a lot of his time in Wooden Indian mode, but is a good enough actor to let us see he's putting it on for Sutherland, whom he constantly shows up, like Tonto telling the Lone Ranger not to step in the kemosabe. Otherwise it's a straight 1980s wrangling buddies movie, in which Philadelphia may be the City of Brotherly Love, but it's portrayed by Toronto, so the frequent gun battle interrupt the bromance.
