Six model prisoners and six socialites go on a picnic at sea. What was supposed to be a simple outing turns into 30 days adrift on a deserted island due to a sudden storm. They engage in deep conversations, sharply pointing out the flaws in our society. They also revel in the mysteries of beautiful nature and lament their spirits, worn down by civilized society. When the unexpectedly prolonged 30-day picnic ends and a rescue ship appears, they each return to their respective places in society. All the latent flaws and contradictions of modern humans are clearly reflected in the transparent mirror of the deserted island, yet they are people unable to escape modern society.
