Six people - a retired scout, a policewoman, a stage girl, a female college student, a local mute girl, and a gangster - were trapped in the fraud park. They planned an escape. Going through heavy rain, jungle, siege by hunters and chasing wolf dogs, every step is a gamble for life. Some people stayed behind and never came back. This is a group of crushed people, supporting each other in a desperate situation and fighting an impossible way out. The journey back was stained with blood, but the light of humanity was as bright as the word "China" on the boundary monument.
