Towing huge piles of logs was always a very dangerous operation. When the snows began to melt and the rivers swelled it added to the danger. Because of the sudden rush of water that it could cause, log jams had to be carefully untangled. One day, a particularly nasty log jam had occurred and Big Mac was being helped by Sunshine to try and clear it. Before Big Mac could stop him, Sunshine rammed into the high log jam and found himself trapped. Ten Cents arrives to help Big Mac free Sunshine, but one false move could spell disaster.
