Synopsis：Sometimes, the person lying next to you is more dangerous than a wild beast. In 1925, in a small border town between China and Russia, a starving Siberian tiger roams the snow in search of food. Railway engineer Qian Cheng saves the beautiful Yaohua from the tiger's jaws. Coincidentally, they were college classmates. Yaohua's newlywed husband sinks into fear, growing increasingly hysterical. A confrontation, bullets from a gun, the Siberian tiger, blood, and a car form a vortex that pulls everyone in. What Yaohua never expected was that her gentle husband would change completely.
