Over a century ago, the Tucks - Ma, Pa, and their sons Miles and Jesse - drank from a forest spring. Ever since, no one in the family has aged a bit. Now they have to live separately only to reunite once every 10 years because of rising suspicions when they never age. Now, young Winnie Foster is out exploring the woods, and she has accidentally discovered the Tuck family secret... which brings her to the question: Is living outside the rules of time a blessing or a curse?
