Thursday Murder Club

Among the peaceful English landscapes live four friends. They have an unusual hobby: once a week they gather to discuss unsolved crimes. Elizabeth, Joyce, Ibrahim, and Ron call themselves the "Thursday Murder Club." All of them have already passed their eighties and live in a retirement home, but they have kept their sharp minds and some other talents.
When a local builder is found dead, and a mysterious photograph is discovered next to the body, the "Thursday Murder Club" suddenly gets a real case. Soon it becomes clear that the first corpse is just the beginning and that our heroes have their own secrets. Will the four retirees be able to catch the killer before it's too late?
