Nelly en haar hond Londen gaan de herfstvakantie doorbrengen bij haar oom Hannibal. Al snel merkte ze dat hij geen rustig leven leidt. Haar oom is een Monster-agent. Nelly wordt meegesleurd in een avontuur vol geesten, vampiers en weerwolven.
Nee, helaas is Nelly Rapp - monsteragent nog niet beschikbaar op Netflix in Nederland.
