When Ruth Handler walks into the boardroom of the toy company she co-founded and pitches her idea for a doll unlike any other, she knows what she's setting in motion. It might just take the world a moment to catch up. In 1956, the only dolls on the market for little girls let them pretend to be mothers. Ruth's vision for a doll shaped like a grown woman and outfitted in an enviable wardrobe will let them dream they can be anything. As Ruth assembles her team of creative rebels - head engineer Jack Ryan who hides his deepest secrets behind his genius and designers Charlotte Johnson and Stevie Klein, whose hopes and dreams rest on the success of Barbie's fashion - she knows they're working against a ticking clock to get this wild idea off the ground. In the decades to come - through soaring heights and devastating personal lows, public scandals and private tensions - each of them will have to decide how tightly to hold on to their creation. Because Barbie has never been just a doll - she's a legacy.
