The Queen of the North is British Columbia Ferry Services' crown jewel, a luxurious, 410-foot ship that cruises the west coast of Canada. But on March 21, 2006, disaster strikes when the passenger ferry strays off course, hits an island, and fills with icy water. Two passengers are never found, and Canada's Transportation Safety Board immediately launches an investigation. Facts are hard to come by, but rumors of an extramarital affair between two of the bridge crew spark a surprising theory about the ship's final moments.

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.
