An Ocean liner called Vienna is to come into Bigg City Port but Lillie Lightships needs to refuel, if there isn't a light Vienna can't come. Supplies are low, Ten Cents and Sunshine try to find oil for Lillie but they only find one which Zorran has and he won't give it to them, He says it's for Vienna. Sunshine knows where to find a light barge. Zip and Zug get the wrong end of the stick and trap Ten Cents and Sunshine by using a fire barge.

Both fleets are waiting anxiously for Vienna but there is no light. Luckily Warrior saves the day by setting his garbage barge alight for a light for Vienna. Ten Cents and Sunshine wait for the tide to set them free. Vienna comes to Bigg City, the tugs do their job and she goes on her way.
