Blue Streak

When a heist goes wrong, thief Miles hides a diamond at a construction site before he's arrested. After serving two years, Miles returns to the location of his treasure and finds it is now a police station. Disguising himself as a recently transferred officer to infiltrate the building, Miles stops an escaping thief while trying to retrieve the jewel. Impressed by his quick action, superior Rizzo partners him with the bumbling detective Casey.
