The Trailer for AMC's 'The Beast Must Die' Promises a Tense Revenge Tale

The first trailer for AMC's upcoming revenge thriller The Beast Must Die has arrived, and the slick, tense clip promises a series full of twists of both the literal and figurative variety.

The series follows the story of Francis Cairnes, a grieving mother who vows to take matters into her own hands after the police investigation into the hit-and-run accident that killed her young son has been dropped without anyone arrested for the crime.

Posing as a novelist researching a murder mystery she's writing, Francis works to ingratiate herself into the family of George Rattery, the man she believes to be responsible for his death, with the goal of taking the first available opportunity to kill him. But when Detective Nigel Strangeways - himself already suspicious that the police department may have helped cover up George's involvement in Martie's death - discovers Francis living with the Raffertys, he throws himself back in the case to try and solve it before anyone else meets a tragic end.
