Frank is an 11-year-old boy who lives with his parents and his little sister who is very lively and defines herself as a little monkey. But the girl gets sick and dies. Frank is very sad for this. But one day, he finds a real monkey in his family’s backyard. Frank is sure: it isn’t a real monkey but his sister who is back. Starting from that moment, Monky is always with him and they have fun together until someone from the neighbors notices the presence of the animal and does not like it. Frank and his parents, who in the meantime are trying to solve their economic problems by creating an adventure park, will have to decide what to do with Monky.
