Sang-hyeon (Song Kang-ho) is the owner of a launderette and a volunteer at the nearby church, where his friend Dong-soo (Gang Dong-won) works. The two run an illegal business together: Sang-hyeon occasionally steals babies from the church’s baby box with the help of Dong-soo, who deletes the church’s CCTV footage that shows a baby was left there, and they sell them on the adoption black market. But when a young mother, So-young (Lee Ji-eun), comes back after having abandoned her baby, she discovers them and decides to go with them on a road-trip to interview the baby’s potential infertile parents. Meanwhile, two detectives, Soo-jin (Bae Doona) and Detective Lee (Lee Joo-young), are on their trail.
One gunshot, one death, one moment out of time that irrevocably links eight minds in disparate parts of the world, putting them in each other’s lives, each other’s secrets, and in terrible danger. Ordinary people suddenly reborn as “Sensates.”
