Bancroft, a brilliant copper has given her life to the police force. Consequently, she's trusted and adored by her colleagues and promotion to Detective Chief Superintendent looks assured. Bancroft runs an operation to bring down the pernicious and vicious Kamara gang. She adopts dubious methods, but the most violent brother, Athif, rules the local town with an iron fist, so it's hard not to applaud her actions.
