Sweet talker (1991)

When scam artist Harry Reynolds gets out of jail, he makes his way to the depressed coastal village of Beachport, where according to local myth, an old Portuguese treasure ship lies buried in the sand. Harry is an old pro at manipulating this situation to his best advantage, but never anticipates how deeply he will be affected by the relationship he develops with a young boy and his mother. A delightful tale of greed, gullibility and grandiose schemes, "Sweet Talker" is a romantic comedy for everyone in the family.
