When Jack refers Zoe for a position in a prestigious professor’s lab, the two become entwined as colleagues. They find themselves on the cusp of a breakthrough: the promise of immortality through a novel anti-aging drug. Zoe and Jack set off on their new project in secret. Finding encouraging results, they bring their work to an investor, drop out of Harvard, and form a startup.
