Atti is een Romeinse tiener met veel verstand maar met weinig spieren. Als één van zijn plannen in strijd is met de visie van keizer Nero, wordt Atti naar het koude, natte Groot-Brittanië gestuurd aan de rand van het Romeinse Rijk. Hij wordt er gevangengenomen door Orla, een pittige Kelt, maar ze besluiten om toch op een akkoordje te gooien. Als Atti teruggestuurd wordt naar zijn regiment, merkt hij dat hij het opneemt tegen Orla en haar stam in de Slag bij Watling Street.
Nee, helaas is Horrible Histories: The Movie - Rotten Romans nog niet beschikbaar op Netflix in Nederland.
