In August of 2017, experienced hunter and avid outdoorsman, Jeremy Evans, was scouting for sheep in the Alberta Rockies when he spotted a grizzly bear cub through his binoculars. Without warning, he was attacked by a mother grizzly bear from behind resulting in devastating injuries. 

Alone in the backwoods of the Canadian wilderness, his face torn, fingers broken, tendons severed, and blood spilling from his injuries, Jeremy struggled for miles to save himself.
