After traveling across the country fighting aliens with his Grandpa Max and cousin Gwen, Ben returns home to face his biggest challenge yet - just being a regular kid, in a town where no one knows he's a hero. Little does he know that under his sleepy little hometown of Bellwood lies a secret, one that he must protect from falling into the wrong hands at any cost. Ben has to go hero and face off against Eon, an evil alien with the power to control time itself, who seems to have a personal connection to the Omnitrix.
