A serial killer called the Hydra is killing people seemingly at random across New York, each murder accompanied by a rather creepy animation of a multi-headed snake. Inspector Queen (Harry Morgan) is making no headway with the case so calls upon his nephew Ellery (Peter Lawford) to help out. Ellery discovers a link in the murders, with the help of one of the victim's sister Celeste (Stefanie Powers).
Ellery discovers a prime suspect, though as the film is only half-way you know there will be some complications...
Not a bad film, though the casting of Ellery Queen is a bit odd. Although the plot is fine, it is stretched out rather thinly which ends up making the film a bit of a drag in the end though it does have a cool filming style throughout.
Luckily for Ellery Queen fans another attempt to launch a TV series starring the character was successful later in the decade.
