NBC’s one-hour drama chronicles the lives of ordinary people who find out they have extraordinary abilities. After a total eclipse, a genetics professor — whose father recently went missing — uncovers a theory about people with superhuman powers. Elsewhere, a young man tries to convince his politician brother he can fly, a teenage girl finds she’s totally indestructible, a Vegas showgirl discovers that her mirror image is a separate being, and an artist (struggling with a drug addiction) can paint the future. Ultimately, this disparate group of folks will be asked to save the world.
