One night, Logger Vick is watching a cartoon about ninjas at home. Briar and Bramble enjoy the cartoon very much through the window. Suddenly the phone rings. It's Vick's boss scolding him for not having his work done on time. Logger Vick doesn't want to lose his job, so he goes out to cut down trees in the dark night. The bears don't allow anyone to damage the forest under their noses. They decide to disguise as ninjas to drive Vick away.
