An expensive painting is stolen, the thief escaping from the top of an office block via a helicopter! The police are baffled, so call upon Sgt Castle (Robert Dix) from the police helicopter squad for help. However, the culprit isn't tracked down before a ransom demand is made which the painting's owner agrees to, his secretary Mona (Merry Anders) is sent to deliver the cash while Castle shadows her in his helicopter. One of the least exciting police car chases in screen history follows.
This can't be said to be a very exciting film but it is very watchable. The lack of much in the way of action actually gives the film a genuine feel and the police procedural work is very solid even if the car chase seems rather inept. The film does feel like it should have been the pilot of a TV series, though Castle says he wanted to leave the helicopter squad anyway!
