In quiet Oakwood, Illinois, mild-mannered accountant Jack Harlan discovers someone is living his life better than he ever did. Using his face, name, and past, a doppelgänger racks up luxury debts in Vegas and Miami, posts glamorous selfies, and even breaks into Jack’s home. What begins as fraud spirals into a chilling game of cat-and-mouse when Jack learns the impostor—revealed as his long-lost twin—intends to replace him completely. With help from friends, family, and sheer stubbornness, Jack confronts his mirror image in a tense diner showdown, fighting to reclaim the ordinary life he once took for granted.
