In the shadows of British Columbia's Comox Valley, a tragic history refuses to rest. Based on chilling true events, Dancing Mary unearths the long-buried story of a young K'ómoks First Nation woman—named Mary by early settlers—who was betrayed and murdered by the very man she once trusted. Her spirit, said to appear as a shimmering blue orb, haunted the area for decades. The last vivid encounter occurred in 1914, when a soldier cycling down Comox Road rode through the ghostly light and described another worldly cold that he would never forget. From that moment on, the legend of "Dancing Mary" was born—named for the spectral sway of her ghostly presence.
