While walking home from her first day at school after her summer vacation, a teenage girl, Anna Grant, finds a beautiful gold and garnet necklace tucked in a box. It appears to have come from the other side of the world. She believes this discovery will be her lucky talisman, but soon discovers it is much more than that; it has the magical ability to grant her every wish!
Gary Kline, a cute boy in her homeroom, had insulted and humiliated her when she had accidentally bumped into him. When she arrives home from school she finds a way to get revenge with the help of the talisman.
Anna makes a wish to get retribution that eventually links her to the nasty boy. Being a talented artist who hopes to become a professional cartoonist, she uses her sketch pad and the talisman to get revenge. However, it backfires and pulls her in to join Gary in an adventure that will change both of their lives forever.
Anna's skill enables her to create mysterious avatars of her and Gary; gorillas that she sketches. They work as a crime-fighting team to make a difference in the lives of people in their community. Their alliance is, for the most part, kept secret, but a few snags and complications cause some folks to guess what is behind the mysterious goings on in their town.
They call themselves 'Monkey Business' and become a force to be reckoned with.
