After receiving a strange package in the mail, "Relativity" follows college student Erin Barclay as she unexpectedly finds herself hosting two strangers, artist Perry and grad student Candace. They are quickly placed in a life or death situation as the object in the package unsticks them from time, causing them to to experience time jumps, but not in the same order. The series is structured so that the same ten episodes can be viewed in three different orders, each order following one character's subjective experience of events.
