Roman teenager, Atti is forced to join the Roman army when one of his clever schemes falls foul of Emperor Nero. He is sent to "miserable, cold, wet Britain" where "the natives are revolting - quite literally". Things go from bad to worse when Atti is captured by Orla, a feisty teenage Celt desperate to prove herself as a warrior.
Unfortunately the movie Horrible Histories: The Movie - Rotten Romans is not yet available on HBO Max.
