When "The Legend" Captain John Selvick brings on a replacement to teach his rookie first mate, Chris Costello, a lesson, his plan backfires. Across Lake Michigan, Captain Ted Long stares down one of the most challenging hauls of his career: six oil containers standing upright at 80 feet tall, prone to being toppled by even a small gust of wind...bringing Ted and his men down along with it. Up on Lake Superior in Duluth, the upstart tug captain Mike Ojard tries to make a name for himself by taking on an ice-breaking job that would challenge a veteran skipper - and nearly gets crushed in the process.
