It's the story of Eddie 'Hudson Hook' Hawkins, a major thief. This man appears to be safe, but he was blackmailed in one theft before retirement. It is a robbery of Da Vinci's artwork to take over the world. If this person refuses, they threaten to kill his friend in one moment.
Let's be clear: 'Hudson Hawk' is, by most reasonable standards, a pretty bad movie. Yet you have to give it this much: in contrast to your typical summer blockbuster, then or now, at least it's got some personality.
