Based on 'Il fu Mattia Pascal', one of Pirandello's many stories concerning the transitory nature of the intangibles "truth" and "identity". Mattia Pascal is a downtrodden average man, treated like trash by his fiancée, scorned by his associates, and cheated out of his inheritance by contemptuous relatives. The dispirited Pascal heads to Monte Carlo, accruing a fortune and also assuming the identity of a less fortunate gambler who killed himself. The "new" Pascal is treated with a dignity and respect that overwhelms him--and nearly kills him.

A dentist buys a small yacht and takes his two children on a cruise of the Mediterranean. His ex-wife stows away to keep an eye on the children and the inevitable happens.
