A possessed Ninja doll teams up with a teenage boy to avenge the murder of a poor child factory worker.

After Phillip Eppermint manages to evade a prison sentence in Thailand, Checkered Ninja comes alive and seeks out Alex. Together, with Alex and his entire family, they now have to go to Thailand to bust Eppermint.

In this 3rd installment Alex’s interest for Ninja missions is starting to vanish. He’ll rather spend his time with his friends and Checkered Ninja feels he is overlooked and is eager to engage in a new mission. The result of this is that Alex, by accident, ends up having a conflict with Marco, the bad boy boyfriend of Jessica, entangling him in a conflict he hasn’t asked for and he is pressured by Checkered Ninja to defend himself.
