When alarms go off aboard the USS Nimitz, first responder Kate Conrad runs to the scene of accidents and injuries. But after 93 days at sea, Kate is suspicious about strange activities in the ship's morgue, so she conducts her own gossipy investigation. Captain Fox, obsessed with the success of the ship's experimental cloaking system, delegates authority over the crew to his executive officer, Captain Brandt. And Brandt, of course, is a psychopath who coerces the ship's medical officer to cover up the problems in the morgue. As the ship approaches the equator, where the crew will hold an ancient hazing ritual, Kate Conrad confronts her superiors with proof of the horrifying activities taking place in the morgue. But they provide no help, so Kate takes drastic action on her own.
