After Anna (Hannah Hoekstra) blacks out after binge drinking at a party, she wakes to find herself with a hangover and a mysterious app called IRIS downloaded onto her phone.

While viewing the film the app would expand on the movie's story line, giving more information about the events and characters as well as showing elements such as different camera angles for specific scenes and newspaper articles.
