This film is adapted from the 2010 South Korean blockbuster and tear-jerking comedy Hello Ghost. A lonely delivery man, A-wei, tries to commit suicide multiple times but fails no matter what he does. Through these failed attempts, he meets four ghosts — a smoker, a crier, a heartbroken ghost, and a mischievous ghost. In order for him to die, he learns that he has to first help these four ghosts fulfill their final wishes. In the process of doing so, A-wei befriends these four ghosts and overcomes his low self-esteem to step out of his comfort zone and experience many firsts in life.
