Snow Trail: Three bank robbers, Eijima, Nojiri, and Takasugi, flee the police and escape into the mountains. At an inn high in the Japanese Alps, Eijima and Nojiri encounter a young woman and her father, as well as Honda, a mountaineer. The inn folk do not realize their guests are wanted criminals and the visitors are treated with great kindness. Honda volunteers to lead them over the mountains, but Eijima's paranoia endangers all of them as they make the perilous trip.
