In the final episode of ALASKAN STEEL MEN, Dennis Butts and his team of master welders find themselves caught up in a series of major white-knuckle crises. A barge off the coast of Anchorage is leaking after getting struck by a large chunk of ice. Dennis and fellow welder Scottie rush to the scene, but the repair goes terribly wrong. Can they fight against the surging seawater and make the repair before completely sinking? Back in Kodiak, Cooper gets his first assignment and is forced to work with a demanding skipper. Meanwhile, office manager Theresa teaches Dean how to settle financial disputes face-to-face. But while driving to see a customer, the two get stuck in deep snow on a remote mountain with no help in sight.
