Lois is away, Hal and Malcolm have a row that ends in Malcolm being banished from the house.

Lois uses a long drive with Malcolm to further his sex education, Reese spends a day in prison, and Francis has trouble branding Otto's favourite cow.

Malcolm requires medical treatment after trying to keep his opinions to himself. Meanwhile, Reese goes on a date with his girlfriend and Craig.

While Malcolm dates a girl whose father hates him, Dewey discovers he's an `evil twin' and Francis mediates a dispute between Otto and his cowboy neighbours.

Hal is inadvertently responsible for a toxic chemical spill that forces a neighbourhood evacuation, Malcolm deals with being grounded, and Francis suffers through a date with a geeky 12-year-old.
