This is a great classic Bruce Lee movie. Bruce Lee is hired by the British Secret Service to infiltrate a drug smuggling ring run by an ex-pupil (Mr Hann) of his Kung Fu school. There are great fighting scenes in this movie, in particular the scene when Bruce Lee is fighting off his enemies in an under ground prison. There is a great cast of Kung Fu fighters, John Saxon, Jim Kelly and famous asian counterparts. Blu Ray brings a new experience to this classic.
