On the Mississippi River in the 1850's, there could be no more romantic dream than to be a steamboat pilot. Braving the hazards of the deceptive, ever-changing river is precisely what Sam has dreamed of, and now, signing on as a "cub" with the pilot of the steamboat Paul Jones, Sam is getting his chance. His journey becomes the adventure of a lifetime, emotionally and physically tested by the river, his employer, and braving the disastrous effects of a deadly explosion. Starring Robert Lansing and David Knell.
