Yeok, a middle-aged teacher raising a son and a daughter alone, witnesses students fall to their deaths from the rooftop of the school where she works. Discovering that her daughter Hyejeong was also present at the scene, she presses her for answers, but Hyejeong only repeats the same words: 'There was a bird in the sky.' As the strange, unexplained deaths continue, Yeok, together with a reporter covering the case and a streamer who runs a birding channel, head towards the birds’ habitat.

Yeon is an ordinary woman in her mid-30s who is ambiguous everywhere—a story about things coming up to her.
