Set in a post-apocalyptic world, Y is the last surviving male human on the planet. Based on the comic series "Y: The Last Man."
On July 17, 2002, all living mammals with a Y chromosome—including embryos and sperm—simultaneously die, with the exception of a young amateur escape artist named Yorick Brown and his Capuchin monkey, Ampersand. Many women die as a secondary effect of male deaths, such as plane crashes. Society is plunged into chaos as infrastructures collapse, and the surviving women everywhere try to cope with the loss of men, and the belief that, barring a rapid, major scientific breakthrough or other extraordinary event, humanity is doomed to extinction.
