It was a stroke of genius, but now the perfect crime is turning into a perfect disaster. Charles, Roger and George are the very picture of honest security guards. But when they learn their favourite artworks are being sent to another museum, they concoct a plan to switch the real masterpieces with fakes. All goes well until a mistake forces these first-time thieves into a last-minute escapade. An amiable heist movie that relies quite heavily on how fond you are of the three leads.
