Genealogist Sophie McClaren is an expert at bringing families together. When her close friend Jonathan urgently needs to find a bone marrow donor, the case becomes personal.

One morning, when Riley (Chantel Little) should be at classes, her mother Angie (Maissa Houri) hears a cellphone ringing from her bedroom, soon to discover Riley left her phone behind. She answers what is Riley's best friend Mackenzie's (Willow Mcgregor) third attempt to reach someone. After Angie asks if Riley is with her, she realizes Mackenzie was about to ask the same thing. Shortly after, Angie checks the main closet and finds Riley's shoes are still there. Did she leave in the middle of the night or vanish into thin air? Riley's circles paint a picture of the events surrounding her disappearance while exploring leads in what becomes a harrowing mystery of twists, turns, and answers that poses the question: Was it better to not know what really happened after finding out the truth?
