It's not uncommon for women, when questioned about their age, to claim they are perpetually 29. But for Adaline (Blake Lively) it's a fact. For nearly a century, she's been celebrating her 29th birthday. She's successfully kept her strange secret largely by keeping to herself. But when she meets the handsome Ellis (Michiel Huisman), she faces a turning point. Also starring Harrison Ford and Kathy Baker.
