Return to the North! (北へ還れ! Kita e Kaere!) is the twenty-fourth episode of Ultraseven.
An Ultra Guard patrol craft mysteriously crashes into a commercial plane in mid-air. The Ultra Guard investigates the incident. Meanwhile, Furuhashi's mother visits him in an attempt to coerce him to quit the force. At that time, Furuhashi is airborne in the Ultra Hawk 3. A beam emanating from a lighthouse has somehow caused the Ultra Hawk aircraft to malfunction, forcing it on a collision course with another airliner. The lighthouse is actually an alien base doubling as a UFO. Ultraseven and Windom (one of his capsule monsters), attempt to destroy the Kanan base before Furuhashi collides with the other plane potentially killing 300 people.
