It all starts out when the Eds are building a pool full of gelatin. Ed ruins the scam as usual and they decide to go back to his house for more gelatin. When they get to Ed's basement Edd and Eddy stumble onto signs saying ""Don't Miss,"" ""All Day Movie."" Ed tells them that the signs remind him not to miss the monster movie marathon. Edd and Eddy decide to watch the marathon also but Sarah and Jimmy kick them out while they're getting snacks. They also try to get into Kevin's house to watch it but that plan fails. Finally they go to Rolf's house and get to watch. Edd and Eddy are not impressed and they and Rolf are stuck watching the marathon.
