 When Dougall has a rough landing while docking the tug, Transport Canada officer Fred Vincent insists that Dougall get an eye exam before his license is renewed. Vincent and his assistant Duvall get stranded due to a boat engine failure, and Dougall responds to the distress call. Dougall reasons that by going through a treacherous passage called "The Needle" he can reach the disabled vessel hours before expected and Vincent will leave him alone. However, Dougall s eyesight fails and it is up to Billy to pilot the tug safely through. The doctors determine that Dougall requires only minor eye surgery and Dougall and Fred trade light-hearted insults in the hospital room.
