Based on Mohsin Hamid's bestseller, "Exit West" centers around the global refugee crisis. In an unidentified country, young Saeed (Riz Ahmed) and burqa-wearing Nadia flee their home after Saeed's mother is killed by a stray bullet and their city turns increasingly dangerous due to worsening violent clashes between the government and guerrillas. The couple joins other migrants traveling to safer havens via carefully guarded doors. Through one door, they wind up in a crowded camp on the Greek Island of Mykonos. Through another, they secure a private room in an abandoned London mansion populated mostly by displaced Nigerians. A third door takes them to California's Marin County. In each location, their relationship is by turns strengthened and tested by their struggle to find food, adequate shelter and a sense of belonging among emigrant communities.
