Dr. Bob Thompson and three friends from Michigan travel to Moose Bay Lodge on Reindeer Lake in northern Saskatchewan, Canada, to fish for big northern pike and lake trout, having no idea they’re about to get caught up in a murder mystery. The friends are assigned a First Nations Cree Indian fishing guide, Oliver Bear, who Thompson knows from previous trips to the lodge. Oliver leads them to the big fish. Oliver has also discovered the location of a valuable secret on the lake – and he is cruelly tortured and murdered in a Sun Dance ceremony to reveal that secret. The First Nations warrior says nothing, forcing whoever killed him to find some other means to find what they seek. Knowing that Thompson has assisted law enforcement agencies to solve and prosecute murder cases in Connecticut and Michigan, the Royal Canadian Mounted Police ask him to assist in the case. Working with Canadian authorities, Thompson makes it his mission to find out what happened to Oliver and bring his killer – or killers – to justice.
