As part of a sequel to "Pooka!", a bunch of friends who knew each other from the high school create their own holiday and a meme challenge revolving around the toy Pooka, the history of its creation, as well as an urban legend revolving around the homicide of its creator who was fired from the toy company that she worked at. When the Pooka Challenge goes viral on the internet, events turn into a living nightmare as murderous versions of Pooka start to come to life.
