Three-year-old Ruby moves into the powerful Hart family estate with her mother, Erin, but no one knows the truth about her extraordinary gift: whatever Ruby says can become reality. A storm stops at her command, her paralyzed brother Noah begins to regain the use of his legs, and her traumatized sister Ava slowly finds her voice again. Ruby can even stop a runaway truck with her tiny hand.
But when the world discovers the mysterious “Lucky Girl,” Ruby’s innocent gift attracts investors, opportunists, and dangerous strangers who want to turn her into a fortune-making miracle. As the Hart family struggles between relying on Ruby’s power and protecting her childhood, they must prove that their love has nothing to do with what she can do. Because even if Ruby never makes another miracle happen, she is still the little girl they would do anything to protect.
