Allow us to set the scene for you. This story starts in the freezing outback of Russia. Specifically, we're in the northwest of the country in a place called Lake Vygozero. This isn't somewhere you'd want to dive off your boat and go skinny dipping.
At its coldest, the water temperature here can sink as low as -4 Fahrenheit. It is, however, an excellent spot to go fishing. Wherever there are fish swimming around in fresh water, there will often be bears. Lake Vygozero is no exception.
