Night shift taxi driver MA KWAI (Kenneth Ma) who lost his parents during childhood has had multiple narrow escapes, which shapes his attitude towards life, seeking not meritorious achievements but only avoiding blame. However, the name of CHONG TSZ-YEUK (Mandy Wong) has left lingering feelings in his mind and heart. Each day, he drives this female doctor to and from work on time, cherishing the moments they share, without realizing that he is meant to be her guardian. It all starts on a midnight. When MA KWAI is urinating on a highway, he accidentally breaks the spell placed on the hundred-year-old Genie, SHEK KAM-DONG (Hubert Wu), and has had many inconceivable experiences ever since.
