Donald Pleasance is the the leader of the Knights of Avalon, a modern-day medieval society who have jousting tournaments at their large castle. They take justice into their own hands by kidnapping criminals in London and subjecting them to trials, which inevitably lead to their death. When one of their own discovers what is going on, he is brutally killed by the others. His son arrives from America and teams up with a retired Scotland Yard commissioner, who wields a wicked umbrella, to uncover the killers. Although filled with violence, it often resembles a made-for-TV Sunday night mystery. Barbara Hershey looks pretty but doesn't have much to do as the love interest.
