Will they hit the right notes this holiday season? When Sadie and Max are selected as contestants on the famed reality singing show STARMAKER's special festive season, Sadie thinks she's finally gotten her big break - and Max sees a chance to step out of his megastar father's shadow. But then they're paired up for duet week and stun the world with their onstage chemistry... With fans going wild for #Saxie, the judges demand they remain a duo - on and offstage - or exit the competition. Faking a relationship shouldn't be too hard, except for one small problem: Sadie and Max can't stand each other. But with their dreams just within reach, they agree to the ruse. Will their relationship lie be exposed before they can win? Or might their fake connection turn real by the Christmas finale?
