Leon Reyes, tight end for the Denver Storm, plans to spend the Christmas break training and playing video games with his childhood buddies. His plans don’t change when quarterback Will Kent bets him to contact his first love and try to rekindle the flame, because his first love is happily married with two kids. What Leon didn’t count on was rescuing his back-door neighbor and junior-high crush, Sadie Jones from a dog attack. His friends then double-dog-dare Leon to bring Sadie to the block party, and Leon never backs down from a dare. The dare leads to a kiss, and Leon is swept away by things he’d forgotten about Sadie. Things he didn’t realized he wanted.
All Sadie Jones wants is a quiet Christmas to finish her business proposal and forget her jerk of an ex, Brian. When she hears Leon and his buddies in their back yard she goes over to tell them to shut up so she can work, but ends up getting attacked by a dog, and saved by Leon. When he asks her to the block party she accepts. When he kisses her she slaps him. When he decides to make it his personal mission to help her rekindle her inspiration for writing she begins to remember why she had a crush on him all growing up, and why she keeps saying yes when he asks her out.
When Sadie’s ex tries to take her proposal, and Leon sends his massive Twitter following after the guy, everything falls apart. Can they put their own issues aside and salvage their budding relationship, or will the Grinch get his way?
