1. In the aftermath of Halloween, Mac, KJ, Tiffany and Erin, four newspaper delivery workers, toured the morning. Their itinerary crossed that of a group of violent individuals with unknown language; and that of a mysterious machine whose everything seems to indicate that it would not come from the Earth...2. Killing birds invaded the sky. On their backs, the ancestors captured the inhabitants and chased the time travellers. A conflict of generations in which the girls found themselves projected... in 2016!3. After having made a leap into the future and discovered the existence of creatures all more dangerous than each other, it is time for the four girls to update the secret origin of the journey in time... at the risk of never being able to return to their lives in 1988.4. The journeys through time-space multiply for Erin, Mac, Tiffany and KJ but do not look alike. After having been torn up at their time the four friends discovered the improbable 2016, before making a brief stay in a prehistoric past where some time Qanta Braunstein was taught them in time that they had the improbable 2016 before.
