Plot Synopsis

Set in 43AD, BRITANNIA is a scripted drama series that follows the Roman army as they return to crush the Celtic heart of Britannia, a mysterious land led by warrior women and powerful Druids who claim to channel the powerful forces of the underworld. The mysterious and tumultuous land of Britannia was occupied by many warring tribes, but all tribal disputes were sidetracked with the arrival of General Aulus Plautius leading his army of Roman invaders, forcing Celtic rivals Kerra and Antedia to face the oncoming invasion that seeks to dismantle the Celtic Resistance. The invasion is only foreseen by rogue Druid Divis, where on his secret mission to overthrow the Romans, he finds an unlikely ally in a young Celt girl, Cait. King Pellenor is convinced his people can destroy the Romans using force, but Kerra seeks an alternative approach. Cait struggles to connect with Divis, and soon finds she is left to fend for herself. An attempted mutiny goes wrong.
