It's normal to be anxious about the digital permanence of your activity on social media, but according to this film, we might have a lot more to fear from Snapchat messages that disappear forever.
In James Corbett's six-minute Murder On Snapchat, the app that deletes your messages seconds after they're sent is used to commit the perfect crime. It's creepy and dark, and feels like it could totally happen.
And like this film from last year set entirely on a teen's computer screen, the plot is told entirely through social media—all the dialog, and the final twist, happen the protagonist's Facebook, texting, and Snapchat screens. Happy messaging!
