In the wake of a severe winter storm, Captain Nathan Schley--stepson of John "The Legend" Selvick, leads a job for the first time without The Legend at his side. When boats get frozen into the dangerous harbor ice, the job seems destined for disaster. Meanwhile, in Thunder Bay, smoke in the engine room forces Captain Stan to abandon a lucrative job--while his Nephew Nate Dawson wrecks a tug at dock. On the South End, Captain Ted Long is forced to work twice as long--and twice as hard, on a junked out tug, bound for the scrap yard.
