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.

Alex Klein is a bankrupt real estate executive whose life is on a collision course. Not only do the market and his career look like a Trabant from before the fall of the Berlin Wall, but he has a wife who is thriving in success; a family whose habits are driving him insane; clients with bad taste and too much money. Not to mention 14-year-old baristas who think they know the difference between highland coffee beans, picked by virgins at midnight and the coffee from the local supermarket. So there's a lot getting on his nerves, so much so, that one day, when things become real serious, he can only weather the storm in his own repelling way.

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.
