Hammerhead is a dangerous international criminal suspected by British Intelligence of trying to steal NATO defense secrets. In desperation, a young, charming soldier of fortune is called in to match wits and guts in man-to-man combat with Hammerhead. His name is Charles Hood and he operates in London (the wilder parts) and moves on to the Portuguese coast in pursuit of Hammerhead and pursued by pert, kooky London model Sue Trenton.

Judy Geeson vs wet paper bag
4 September 2015 | by milliefanSee all my reviews

The other reviews are pretty spot-on in assessing this as utter drek, but oddly nobody has mentioned the ludicrous scene in which Judy Geeson - worst actress of 1968 without a doubt - suddenly bursts into song. After a good hour (which seems like a lifetime) of Geeson's high pitched, twelve year old schoolgirl voice, she appears in a nightclub 'singing', only her voice has been dubbed by a Madeline Bell soundalike (for those who aren't familiar with Miss Bell, she is a husky voiced jazz singer of the Shirley Bassey type). A more unsuitable voice double for Judy Geeson would be hard to imagine! The only plus in the entire film is the great Diana Dors, injecting interest and style into a project sadly lacking in both departments.
