Plot summary
After Scorpion loses a contract with the Department of Energy to upgrade their server when Walter disagrees with a rep over their "mathematically inaccurate" fee, he takes on a case to use their echolocation tech in search of pirate treasure. The team is hired by a Marine salvage company that believes they've found the San Caldera, a Manila galleon that sunk by Drakes Bay in 1595 carrying a fortune in gold. Meanwhile, Allie helps Sly out with his campaign by getting him an interview with a teenage reporter for the West Altadena Shopper.
However, he has more important matters to attend to when he has to help rescue Walter and Paige when they're stranded in the middle of the Pacific Ocean after their boat explodes from an electrical problem. Even though they're able to make it to a Danish buoy to get out an S.O.S., a frenzy of sharks surrounds them.
