In 1946, ex-Navy engineer Steve Martin comes to a Louisiana town with a dream: to build a safe platform for offshore oil drilling. Having finessed financing from a big oil company, formerly penniless Steve and his partner Johnny are in business...and getting interested in shrimp-boat captain Rigaud's two lovely daughters. But opposition from the fishing community grows fast, led by Stella Rigaud. Other hazards include sabotage, a hurricane...and a treacherous board of directors.
