The trailer depicts Adam (Gabriel Basso) and Katie (Kathryn Prescott) flirting in an idyllic, sunny bedroom. Everything looks perfect — until a plane (or spaceship?) crashes in the distance. The honeymoon phase is over, and what appears to be a disease outbreak consumes their world. Adam documents memories and tries to discover the truth in a fashion reminiscent of Christopher Nolan’s Memento.
