In June, the Shonan coast overlooking Enoshima Island. On a clear day, people who cannot wait for summer to arrive come to see the sea. Families frolic in the water by the waves, couples huddle together. Among the happy people, there is one figure that stands out: a solitary person staring at the sea. Tired office workers, women in love. Even at night, people with various circumstances appear one by one on the quiet beach.... What do people think about on a beach where there is nothing but the sea and the sky? A story of three days waiting for summer.
