The team becomes obsessed with money-lust for a sunken treasure. Their argument about who the unfound treasure belongs to sets Sean off; he thinks they're destroying the team. Jason convinces Sean to permit their treasure hunt by referring to it as a scuba diving exercise and succeeds. The Coast Guard rescue swimmer Nick helps Allie find the areas where they'll most likely find a ship, but warns her that it's very unlikely that they'll be able to locate anything. Sean confronts Dawn with her lack of engagement to the team, and expresses his wish for her to step out of the sideline and into the game. Later on, they are able to locate the sunken ship and dive down to it, but the search becomes dangerous when Jason causes a torpedo to shake loose at the site.
