Drie personen pogen tegen de achtergrond van het digitale tijdperk hun identiteit te behouden. Frankie werkt als serveerster met haar beste vriend slash minnaar Jake. Ze loopt ene Link tegen het lijf die ze zo nu en dan op camera vastlegt vanwege zijn sterke kritiek op de handel. Ook Jake wordt bij de filmpjes, die online viraal gaan, betrokken. Tussen het trio ontvouwt er zich een driehoeksverhouding, maar wanneer Frankie grote veranderingen bij Link bemerkt wordt ze voor een dilemma gesteld.
