Plot synopsis: When the kind-hearted, semi-nerdy, and always-prepared Sarah gets blindsided by a breakup, she finds herself utterly alone, having spent the past four years neglecting every relationship other than the one with her loser boyfriend. She reaches out to the only person she can think of, her messy-but-loveable friend Megan and, together, they embark upon the post-breakup Uber trip of a lifetime.
