In a special underground prison, a system malfunction suddenly occurs, allowing the inmates to escape. However, instead of reaching the desired surface and freedom, they find themselves in a strange underground world, where escape seems unreachable. One of them, with the help of a chicken, gains the ability to levitate, and in this newfound skill, the prisoners see a glimmer of hope for freedom. However, things, as expected, don’t unfold the way they imagined.
