Detective Murdoch and Dr. Ogden travel to Vancouver Island to visit Murdoch’s brother, RCMP officer Jasper Linney. There, they investigate a murder connected to an archaeologist who has uncovered an ancient Indigenous settlement, leading to encounters with the Songhees and Haida nations. Meanwhile, the Brackenreids are offered an investment opportunity that may not be all it seems, and Crabtree and Higgins plan a ski holiday with their sweethearts Nina Bloom and Ruth Newsome that may be more dangerous than expected.
