September Storm on AllMovie

In this standard adventure yarn shown in 3-D, four people on a "borrowed" boat -- three men and a woman -- take off looking for sunken gold worth millions. A young, handsome man (Asher Dann) works on the yacht of a Parisian tycoon who happens to be away at the moment. Two nautical layabouts (Mark Stevens and Robert Strauss) convince the man to take them out looking for the sunken treasure, so the three of them set off on their adventure with a beautiful New York model (Joanne Dru) on board. There is some underwater diving and chasing after the model, and as the title indicates, the violent storm that shakes everyone up and makes this run for gold a dangerous proposition.
