Red Cap is a British television drama series produced by Stormy Pictures for the BBC and broadcast on BBC One. Two series of six episodes each were produced following a feature length pilot. It featured the investigations of an Special Investigation Branch unit of the British Army based in Germany. Ostensibly the lead character was Sergeant Jo McDonagh, played by Tamzin Outhwaite, but the show was more of an ensemble piece, with several notable characters coming to prominence.
