35 years ago, Mickey O'Malley nabbed one of Empire City's most wanted crooks by the name of Suds Sparko, who secretly hid five million dollars in cold hard cash in a secret location. The only vital clue to its whereabouts is a map carved on a bar of soap. Big Boss sends Rock Krusher and Buttons McBoomBoom to steal the soap. But a mishap occurs and the map is completely dissolved. So, the two crooks kidnaps Mickey and Brian and take them to where Krusher knows exactly where the loot is stashed at – The West Side Laundry, where Mickey will have to figure out where at the place the loot is stashed at – and help LongArm and Barricade send the criminals to the cleaners.
