Don, a chubby boy bullied as "Jumbo", encounters Meri, a spirit seeking help to reunite with her troubled family's spirits. Their journey unfolds.

Desperate to prove to his peers that he's more than a chubby kid that never wins at anything, little Don wishes to win his local talent show by performing a stage play inspired from a story book written by his late parents. When unfortunately a bully stole that book, at the same time a little ghost appeared from the spirit world asking for Don's help to reunite her with her parents' spirits. The two new friends then embark on an exciting adventure to help each other and learn the true meaning of friendship.
