3 Ninjas Kick Back — 50 years ago, a master samurai fought in a ninja tournament to win a magical dagger that, along with the sword of the ancient samurai, is believed to be the key to unlocking a secret cave laden with riches. After winning the tournament and rightfully winning the dagger, it was stolen by the master's leader Koga. Although the master searched everywhere, he found no trace of Koga or the dagger. Now too old to continue his quest, the master sends his three young apprentices, the young ninja brothers, Rocky, Colt and Tum-Tum, to help him obtain the valuable dagger.
