Reese is getting bad grades in school, and so Malcolm is forced to tutor him. Meanwhile, Francis comes back to visit home again and quickly gets himself kicked out of the house.
The episode begins in the kitchen with Lois ordering Francis to re-shingle the roof because Hal has a fear of heights, even from two feet up. Francis finds it unfair since he immediately put to work after coming home from school the previous day and asks why Lois doesn't just put a choke chain on him and make him sleep in the garage before storming out of the kitchen. Malcolm, Reese and Dewey are all eating cereal while listening in to the fight. Malcolm claims that Lois has entered a "Level 4 Rage" and the only way to avoid it is to make no sudden movements or noises. Reese's spoon accidentally clatters on his bowl, and Lois lectures him on how he hid his parent-teacher interview note, Reese claims his teacher Mr. Woodward is out to get him, Lois then reminds him he has thought every teacher since kindergarten has had it out for him. Malcolm accidentally sniffs and Lois turns her attention to him.
Malcolm tutors Reese to improve his lousy grades, but soon discovers that Reese's teacher is out to get him, which Reese has been claiming all along. When Lois finds out that Malcolm helped Reese cheat she is furious, until she realizes that the teacher put an F on something Malcolm wrote and concludes Reese wasn't just making up excuses.
Francis leaves the family and lives in the basement of his friend Richie's house because Lois kicked him out.
