The paranormal drama's fourth run will begin on Sunday, February 5 at 9pm on BBC Three.
Premiere episode 'Eve of the War' will follow the ghostly Annie (Lenora Crichlow) and werewolves George (Russell Tovey) and Tom (Michael Socha) as they fight to protect a baby from the attentions of vampire overlords, the Old Ones.
The instalment, written by series creator Toby Whithouse, will also introduce new vampire Hal, played by newcomer Damien Molony.
Molony and Socha have joined Being Human as series regulars, following the departure of original cast members Aidan Turner and Sinead Keenan.

In addition, Harry Potter's Mark Williams will play a character named Regus, while Submarine star Craig Roberts will reprise his role as teen vampire Adam.
