Ricky Feeple's your average teen American ninja — with a legendary ninja Mom, a goofball, and a snobby ice-queen for teammates, a girlfriend who's part of a rival ninja team, plus a vampire archenemy he's never beaten and who turned a robot friend against him. Now the vampire's kidnapped the infant daughter of the rival team's trainer, so every ninja in town is out to save her, even ones from teams that Ricky has never heard of before.
