S2, E5: The fishing boat Lady Mary and her crew are hauling scallops in near-freezing waters off the shores of New Jersey in 2009. On their final night, something goes wrong, and the vessel suddenly begins to sink. The freezing waters, coupled with a delayed response from the Coast Guard, lead to the death of six of the seven men onboard. It’s up to the Coast Guard to find out what happened and why emergency units weren’t alerted until 90 minutes after the ship sank.
