One dark night Uncle Ben, his son Wilbur and daughter Betty together with cousin Kevin are watching the glow over the city when an enemy plane touches the top of the tall trees around the farm house and crashes on one of the fields further on. There is a horrendous explosion and it is assumed that all the crew perished. But no The pilot escaped and the hunt is on by the Police and Royal Air force to find him. That's when the two boys and the girl form their own team to run him down. Wulldog, their fox-terrier, gets involved and the adventure begins.
