Countdown (15)

The Countdown app claims to tell the user exactly how long they have to live once it is installed on a mobile phone. Nurse Quinn decides to try out the app, like many of her colleagues at the hospital, and she is horrified to see that her life expectancy is just two days, 22 hours, 37 minutes and 13 seconds. At first, Quinn dismisses the app but then she hears rumours about users who have apparently died at the exact second predicted by Countdown.
