The amusing "Alley Cat" is a watchable low budget variation on the time honoured "Death Wish" premise with a female lead. It never really catches fire, but it remains a mild diversion anyway - a crude, formulaic, sleazy, cheesy diversion that does deliver some of the requirements of the exploitation genre.
Karin Mani stars as Billie, a young woman living with her grandparents who works herself into a righteous fury when the old folk are targeted by criminal scum. The grandmother is fatally stabbed during a mugging and Billie becomes consumed with the idea of revenge. She meets cute with a nice guy cop named Johnny (Robert Torti) who indulges in some of his own vigilante tactics.
Mani's clearly got what it takes when it comes to the ass kicking department, but in general isn't terribly appealing; Torti scores more strongly in terms of likability. (However, Mani looks so good sans clothes that it's doubtful many people are going to care that much.) Much of the acting is amateurish yet entertaining. Lovely Britt Helfer has a memorable bit as a hooker whom Johnny intimidates into giving up information. Both Jon Greene and Michael Wayne have fun roles as a jerk cop and the prime antagonist of the piece, respectively. Wayne, who sports a scar and is thus named "Scarface", is actually named Krug in the movie, which will amuse any fan of "The Last House on the Left".
There's enough nudity to keep people happy as well as the required shower scene since a plot twist has Billie sent to prison (there's a message in here about the complete unfairness of an incompetent judicial system). One of the cons also makes lesbian overtures towards Billie. The fight scenes aren't the most slickly staged but are basically enjoyable. And the silly music score is just icing on this cake.
It's easy to see why this might be somewhat obscure for its genre but if you're a die hard addict of trash cinema you could certainly do a lot worse.
