A story of an unusual family formed through extreme odds, exploring such hot-button issues as identity, human connection and what it truly means to be a family. An only child finds her life turned upside down when her father reveals that, over the course of his prize-winning career as a pioneering fertility doctor, he used his own sperm to conceive upwards of a hundred children, including two new sisters. As these three young women slowly embrace their new reality, they will attempt to form an untraditional bond as sisters, even as they must welcome a tidal wave of new siblings into their rapidly expanding family.
