A series of discovery and underwater adventure

Three hundred tons of lethal poison lying at 50 fathoms in the hold of a sunken ship can be ignored by some. But not by Italian Judge Maritati in whose waters the rammed Cavtat lay.
When all official requests to remove the deadly threat were refused, Maritati took matters into his own hands. With the help of JACQUES COUSTEAU in Calypso, he commissioned a flotilla of salvage vessels at the cost of 12 million dollars. So for 10 months divers - each one supported on the surface by 150 men from doctors to crane operators - risked their lives amongst poison drums at unbelievable depths in the Adriatic. This story is one man's fight to save the waters of his Italian fishing town, Otranto, from disaster.
