When a young nurse downloads an app that claims to predict when a person is going to die, it tells her she has only three days to live. With time ticking away and death closing in, she must find a way to save her life before time runs out.
And if this story sounds familiar to some, that's because it's based on the French 'bande dessine' (comic book) The Killer by Alexis Matz Nolent and Luc Jacamon.
