The follow-ups to the engaging martial arts movie 3 NINJAS, this trilogy follows the adventures of three young brothers whose grandfather has trained them in ninjitsu. 3 NINJAS KICK BACK sees Rocky, Colt, and Tum-Tum traveling to Japan with their grandfather to help him deliver a ceremonial dagger at a ninja tournament. The trio's martial arts skills will be put to the test by a trio of bumbling thieves and a handful of opposing ninjas. Then, in 3 NINJAS KNUCKLE UP, the mini-ninjas take on a wealthy toxic waste polluter who threatens to obliterate the Indian community. To do this the boys must, against all odds, locate a disk with incriminating evidence. Finally, in 3 NINJAS HIGH NOON AT MEGA MOUNTAIN, the dastardly villains Medusa and Lothar Zogg invade a family fun park and take its summer visitors hostage. Now it's up to the three ninjas to save the day, with a little help from an aging action movie hero who needs to pull off the rescue to regain his street credibility.
