Jarden, Texas was renamed “Miracle” after it was discovered that no one had departed. The town has since become a magnet for tourists and people who are convinced it is special and can keep them safe. Among the local families is the Murphys: the father, John (Kevin Carroll), the mother, Erika (Regina King), and their twins, Evie (Jasmin Savoy Brown) and Michael (Jovan Adepo).
While trying to protect his town from frauds and charlatans, John gets an ominous warning from a man who claims to have psychic powers. Soon afterwards, Kevin Garvey (Justin Theroux), Nora Durst (Carrie Coon) and Jill Garvey (Margaret Qualley) show up in Miracle. This newly formed “family” left Mapleton to start over, but Kevin cannot seem to escape his past. The Murphy family and Kevin subsequently experience a mysterious event that will that change their lives forever.
