Ever since she was a little girl, Iris has wanted to be a filmmaker. For the last five years though, she's been trapped working in reality television, directing episodes for a series that's barely able to compete with Ghost Hunters. Iris sees her big chance to prove herself when she gets sent on assignment to her hometown of Black Falls, a small town harboring an abandoned insane asylum that has a dark history of excessive shock therapy. Filming inside the asylum brings back childhood memories for Iris, memories of sneaking into the asylum with her friends to shoot homemade horror movies. Little does Iris know, her life is about to imitate her art.
Unfortunately the movie The Purgation is not yet available on Disney Plus.
