This is it you guys. We have come full circle. We started with the show with strange deaths in the Russian mountains, and here we are, 8 years later talking about a different case of mysterious deaths in the Russian mountains.    The 2 cases are very similar, yet separated by several decades. So today we speculate about the events that caused the deaths of 6 hikers, leaving only a single survivor.   We hope you enjoy the final episode of the What Cast. Join us next week when we start to Cast some What's.
