Key Largo

In Key Largo, Army veteran Frank McCloud (Humphrey Bogart) arrives at a hotel in Florida to visit the family of an old war buddy who was killed in action, only to find it's been taken over by gangster Johnny Rocco (Edward G. Robinson) and his thugs. The situation escalates into a tense standoff as Rocco forces Frank to take him back to Cuba on his boat, but Frank uses his seamanship and trickery to kill the gang members one by one.
