Three shipwrecks anchor this look at maritime disaster and its aftermath: the tanker MT Haven, which burned off the Italian coast and still leaks oil decades later, the bulk carrier Wakashio, which ran aground on a Mauritius reef and spilled fuel into pristine lagoons, and the passenger ferry Orient Queen, sunk in the Beirut port explosion. Divers descend into each wreck to document corroding hulls, trapped fuel, and the marine life now colonizing the steel, while engineers and salvage crews explain what caused each disaster and why removing a half-submerged tanker or ferry is far harder than sinking one. The film treats each case as both an engineering puzzle and an environmental hazard, weighing containment booms, partial dismantling, and the sheer cost of full salvage against the risk of leaving thousands of tons of fuel oil sitting on a reef or in a harbor. Interviews with divers and cleanup specialists carry most of the narration, grounding the disasters in the specific coastlines and communities still dealing with them.
