In order to reach the island, Walter teams up with Johnny Mason, neighborhood stoner, to smoke up Ashley Valinski, neighborhood hottie, and get her to take them out on her father's boat. But soon after arriving on Cadaverous Island, a horde of zombies steals their boat, leaving them stranded, and the three are forced to team up with two cops, the mayor, and a team of botanists to either kill the monsters... or be killed themselves..... DUN-DUN-DUN!!!
