Based on the works of Suetonius
The story of Caligula begins in a Rome plagued by the paranoia of its current ruler, Tiberius. Innocent citizens are routinely put to death for even the slightest suspicion of treason, and this fate eventually befalls Tiberius' own nephew, Germanicus (Sebastian Arcelus) and his wife more...
(the excellent Shorey Walker). Their son, Caligula, and their daughter, Drusilla, are taken in by Tiberius and raised as his own children, largely because Caligula is considered a threat to the empire. As adults (Euan Morton and Brooke Sunny Moriber), Caligula and Drusilla engage in an incestuous relationship, which further blossoms after Tiberius dies and Caligula ascends to the role of emperor. Forced to take a bride (public opinion scorns the siblings' relationship), Caligula becomes despondent about his title, and after Drusilla's death, he descends into madness, violence and debauchery. He tries to make his horse a senator. He even turns the imperial palace into a whorehouse.
