Who do you- call when thousands of tons of gnarled metal, over 100 feet deep in the water, are threatening to wreak environmental havoc if hot removed immediately? For the people of Louisiana the answer is the Bisso family, as for more than a century they have been building a long history of expertise in the incredibly dangerous and highly technical duty of sea salvage and excavation. At Bisso Marine, death and dismemberment are part of the job - a as a family business, those treacherous stakes are even higher. For each mission, Beaux Bisso and family assemble a team of engineers, divers and renegades to solve a seemingly impossible salvage problem. Hauling up a hunk of collapsed bridge from a river; raising a rust-bucket cargo ship from its watery grave; blasting through the seabed to dislodge gas lines - the Bissos and crew don't just use technology to accomplish their jobs, they often invent it as they go, pulling off a few deep-sea engineering firsts in the process. Watch as extensive CGI details their game-plans, providing a context for these unbelievable underwater missions.
