Four childhood friends connected by a shared tragedy grow up in the same village but lose touch as they grow older. Miao Miao (Rabbit Yang), who is now a newspaper reporter, sets out to find her long-lost friends, whom she only knows by the nicknames Dragonfly, Cricket and Little Grass. Her quest brings her in contact with Liu Tung-han (Penber Pan) and Lin Tzu-yen (Mini Tsai) - members of a special investigation team assigned to protect Miao Miao's best friend, Lo Yung-mei (Angela Chia-yu Lee) - and Shen Tzu-hung (Ting-hu Zhang), a retired special forces officer.
