Ota has yet again totaled his Ingram in the line of duty. Sakaki orders the mechanics to fix the labor overnight. Shige tells him that they can't do it and have been working non-stop, and will probably need a night off. Sakaki is sympathetic to their plight and checks up on the sleeping mechanics. However he finds tons and tons of pornographic magazines and videos in their possession. Enraged, he publicly burns the lot and instigates new rules, banning many popular pastimes such as fishing, and leaving very little of a private life. The mechanics are very upset and Shige decides to talk to Sakaki. Before he can get a word out, Sakaki tells him that he may be retiring soon, and that Shige will eventually be head mechanic. Sakaki tells him that he will have to look after the mechanics and discipline them. Shige takes this talk the wrong way, and forms a force to weed out mechanics who break the rules. This causes the mechanics to revolt, but some don't agree and splinter groups form. Kidnappings and beatings of other mechanics begin. Though the ruckus doesn't effect their work, Sakaki must do something to regain control.
