The Tomorrow War
Synopsis: During a televised World Cup soccer game, time-traveling soldiers from the year 2051 appear on the field with an urgent message for the planet: Thirty years from now, mankind will lose a global war against a terrifying alien species unless thousands of citizens from the present are transported forward in time to join the fight. Among those reluctantly drafted is high school science teacher and devoted dad Dan Forester (Chris Pratt), who is forced to leave his wife Emmy (Betty Gilpin), their young daughter Muri (Ryan Kiera Armstrong), and his estranged father James (J.K. Simmons) behind. Sent to a post-apocalyptic Miami Beach on a perilous search-and-rescue mission, Dan and fellow draftees Charlie (Sam Richardson), Dorian (Edwin Hodge), Norah (Mary Lynn Rajskub) and Cowan (Mike Mitchell) battle the nightmarish extraterrestrials known as “white spikes.” Lightning-fast and armed with tentacles, multiple battle-scarred limbs and mouths filled with rotting teeth, the ravenous creatures slaughter most of the new recruits. But with the help of a brilliant military scientist code-named Romeo Command (Yvonne Strahovski), a wounded Dan and his comrades carry on the fight to save mankind. Recuperating at an army base, Dan learns that the only hope of defeating the aliens is if Romeo Command can use her expertise to devise a biological method of killing the female creatures. To do that, however, they first need to capture one alive. And unless a solution can be found before a horde of white spikes overruns their ocean-based lab, Dan’s family back home – and humanity as a whole – won’t stand a chance.

Desperate for an assignment, John asks his superior, Sebastian, for a new job. The case he receives is that of a troubled girl, Anna, who has begun a hunger strike. While the parameters of the job seem quite simple, Anna proves to be much more challenging than John expected. She’s intelligent, insightful… and possibly one of the most conniving and manipulative people that he’s come across in his career.
