High School! Kimengumi (Movie)

The strange-faced members of the Kimengumi cannot even reach summer vacation without creating trouble. After failing their exams, the boys are stuck with remedial lessons while everyone else is ready to enjoy the break, turning punishment into another opportunity for their usual nonsense.

Summer then brings a school trip to the beach and a swimming competition, followed by a new crisis when classes resume and the karate club faces a threatening challenger. Rei Ichidou and his eccentric friends charge through all three situations with the same mixture of ridiculous confidence, rivalry, and complete disregard for ordinary school behavior.
