One of the defining films of the 1970's, this was the film that took Clint Eastwood from cult hero to mainstream superstar. A true classic. This a rare UK quad from the first UK release. Cop Harry Callahan (Clint Eastwood) attempts to track down a psychopathic rooftop killer before a kidnapped girl dies. When he is found Harry abuses the murderer's civil rights putting him back on the streets. Once he is released he hijacks a school bus and Harry must go after him again. The only way to stop this vicious killer is in cold blood.
