S1, E1: Returning to New York from a family vacation in Jamaica, the Stone family is separated when adult siblings Michaela (series star MELISSA ROXBURGH) and Ben (series star JOSH DALLAS), along with Ben’s gravely ill son Cal (series star JACK MESSINA), are bumped to a later flight, while Ben’s wife, daughter and parents fly ahead. When that later flight lands, the passengers are bewildered to discover that five and a half years have gone by. They attempt to reconnect with the loved ones who mourned their passing and moved on long ago, and try to make sense of a mystifying phenomenon steering them to act in ways they don’t understand. The series premiere also stars ATHENA KARKANIS as Grace Stone, J.R. RAMIREZ as Jared Vasquez, LUNA BLAISE as Olive Stone and PARVEEN KAUR as Saanvi Bahl.
