In the heart of a quiet town, a young woman tends to her plant shop, but beneath the soil of her lush, green sanctuary lies something far darker....

Every garden needs a little weeding ...

Tucked away in the corner of a neighbourhood in Dosan, South Korea, is the Plant Shop. Its owner Yoohee has started anew, while her meticulously grown foliage thrives under her tender care. The shop is her refuge, where petunias and marigolds bloom and the air itself is like an elixir of peace.

By day, Yoohee dispenses gardening advice, but she also finds herself offering a special service out-of-hours. Women in desperation come to her about a man they hope might disappear from their lives.

As more men are reported missing, a determined young detective comes knocking ...
