Mia possesses a unique supernatural perception that displays a glowing numerical loyalty rating above every person's brow. For six years, her childhood partner Jack displayed an immaculate hundred, until an office intern entered his life and caused the digits to plummet. The instant Jack's number drops to zero, Mia packs her bags and walks out of his life without an argument.
Refusing to mourn a hollow romance, Mia focuses on competitive distance running and crosses paths with Ethan, an unassuming peer from her past. To her amazement, Ethan's loyalty rating has remained anchored at an unwavering hundred since their school days. While Jack frantically stalks her with desperate pleas for reconciliation, Mia gives her devotion to the man whose fidelity never cracked.
