 Dennis flies to Sudbury on a routine "milk run" and takes Billy along with him. While they are getting airplane parts from Shorty, Russ Jordan is eluding the police, steals a gun and stows away in Dennis  plane. During the return flight, Jordan holds the gun on Dennis and demands to be taken to Sault Ste Marie. Dennis is forced to land on a remote lake when a storm breaks out, but there is not enough water and the plane beaches. Dennis is knocked unconscious and Billy and Jordan assess the damage. The pontoons can be easily repaired, but Dennis very badly hurt. Jordan had taken flying lessons and flies the plane out, heading to Sault Ste Marie. Billy pleads with Russ to take Dennis to a closer hospital, which he is reluctant to do.
