After her fiancé is killed and she is almost sexually assaulted, a woman becomes an avenger of the night, seeking to kill all the dangerous men who would harm women. Meanwhile, her fiancé's cop brother also seeks to bring down the biker gang associated with the murder.
A baffling movie for which the production started in the late '70s/early '80s. The project was eventually completed in the mid-'90s, but the movie wasn't released until 2005.
Complete with cameo by fake Stan Lee, it looks like.
