The 'Maggie' (High and Dry) Maggie (1954)

The poor, elderly—and the wily, when it comes to parting those who can afford it from their money—Scottish skipper of a broken-down old 'puffer' boat tricks an American tycoon into paying him to transport his personal cargo. When the tycoon learns of the trick, he attempts to track down the boat and remove his possessions.
