Sixteen-year-old Cara has cerebral palsy. Self-conscious about her limp, Cara is convinced her disability is what causes boys to always place her in the friend zone. This summer, it seems to be happening again with her new crush, Josh. The two of them are huge fans of a popular mystery podcast and, as it happens, Cara has a real-life mystery of her own. She's never been that curious about the donor who is her biological father, but now that Josh shows an interest in learning his identity, she's all in. As Cara starts exploring, she stumbles upon a family secret that just might explain the feeling she's always had that something important is missing from her life. But with this knowledge, her life may never be the same again.
