Jacob King (Steven Seeger Steven Seagal) is an agent in Memphis, USA. On his 10th birthday, twin brother Daniel was brutally killed, which left an indelible shadow in his heart and may indirectly affect Jacob's style of handling cases. He is frank and rude and often takes violent measures to deal with suspects. Although numerous cases have been solved, they have been severely criticized both inside and outside the police station. Soon, a series of homicides occurred one after another, and all of the dead were left with mysterious astrological symbols. During the investigation, Jacob did not get involved in a series of troubles and was even framed as a serial killer. At the same time, the crazy Billy (Mark Collie), which Jacob caught with his own hands, was successfully freed. He went on a killing spree and took revenge on Jacob. The screenwriter of the film is written by the leading actor Steven Seeger himself.
