The series follows DI Moses Jones (Shaun Parkes), a Scotland Yard detective who is seconded onto an enquiry investigating a mutilated body found floating in the Thames.

[2] The discovery of the bizarrely mutilated body in the Thames who seems to have been the victim of a ritualistic witchcraft killing sparks a wave of violence amongst London's Ugandan exile community.

DI Moses Jones (Shaun Parkes) is seconded to the case from Scotland Yard due to his supposed cultural links with the local African community and assisted by young, hopeful DS Dan Twentyman (Matt Smith), he sets out to uncover the truth.

As the investigation continues, the violence escalates and the evidence all seems to point towards Matthias Mutukula (Jude Akuwudike), a mysterious godfather figure rumoured to have both terror links and supernatural powers.

Forced to ask himself tough questions about his cultural identity, Moses Jones embarks on a frightening quest to track down his man and redeem himself before the community implodes... or takes revenge itself.
