There is a mugger in Gotham City, and the attacks seem to be random. Four attacks, all males between 31 and 53, each with different jobs and ethnic backgrounds. Finally, Robin and Batgirl catch a lucky break--a video camera aimed on one of the muggings. They couldn't actually see the muggings, but they saw a witness: Big Vinnie, the bookie! They finally find out the link: all of the victims are coaches in their 12 year old sons' hockey league! But can Robin and Batgirl get their in time to save the last coaches?
