An epic drama set in 43AD as the Roman Imperial Army – determined and terrified in equal measure – returns to crush the Celtic heart of Britannia – a mysterious land ruled by warrior women and powerful druids who can channel the powerful forces of the underworld. Or so they say.

Police duo Bishop and Pike are two best mates bonded by the same moral code, despite their differences. Packed full of humour, action and emotion, Bulletproof is about friendship, conspiracies and ghosts from the past.

The series follows John Porter, a former British Special Forces soldier, who is drafted back into service by Section 20, a fictional branch of the Secret Intelligence Service.
