Two men try to carjack the Rust Bucket while Grandpa Max and Gwen are out. Fortunately, Ben is still on the Rust Bucket and the carjackers end up messing with Ben after he transforms into Four Arms. Four Arms fights off the carjackers but then the Rust Bucket goes out of control. Four Arms tries to drive, but the carjackers hose Four Arms and he accidentally turns on the booster; however, Four Arms turns it off again. Four Arms ties up both of the carjackers and throws them out without Grandpa Max's and Gwen's knowledge of the incident.
