Discovery's "Shipwreck Men" features modern day pirates patrolling the coast of southern Florida - and the bounty they're after is boats in distress. Salvage companies scan the waters day and night. When trouble strikes, they race into action, whether it's saving a sinking vessel, rescuing boats from dangerous hurricane storms or putting out a massive fire. While their intentions are good, it doesn't mean it isn't a cutthroat business.
