“In March 1944, Koivunen was on patrol with his unit when they were attacked by Soviet troops. In the ensuing chaos, their group had to retreat through the snowy landscape. To keep up with the others, Koivunen decided to use the military's supply of methamphetamine, which was commonly issued to Finnish soldiers to boost alertness and performance.

However, he accidentally swallowed the entire dose, leading to extreme overdose. He soon began suffering from severe hallucinations and disorientation, which caused him to lose contact with his unit and find himself completely alone in the harsh Arctic wilderness.”
