Blue (2009)

In 1947, a ship carrying loot worth millions of dollars sank near the Bahamas Islands, and an innocent man was blamed for it. The treasure is still hidden at the bottom of the ocean. Years ago, the last man who knew where the treasure was buried died trying to find it. Now there are four people vying for this sunken treasure, and none of them will stop at any cost. A Mafia Don wants it for personal gain, another needs it to save his life, yet another must overcome his past demons and go after the treasure to save his brother's life, and yet another wants it at all costs for personal purposes, such as the urge to win.
