Holly Jolly July

It's the hottest Christmas on record...

Like naughty and nice, Mariah and Ellie are complete opposites. Small-time actress Ellie is thrilled to be back on set of a cozy holiday film, while makeup artist Mariah only views the low-budget project as a stepping stone on her way to more serious movies. The pair definitely don't hit it off when they're introduced, but if they want to survive the summer heat -- and Mariah's stifling Canadian hometown -- they've got to keep it professional. Luckily, holiday cheer is Ellie's specialty, and she's determined to win stubborn Mariah over.

Mariah finds one bright spot in her forced second Christmas: hot hookups with an edgy local bartender. The romance even has her opening up to Ellie -- who admits to crushing on her wholesome cottage-rental host. But when Ellie and Mariah realize the guys are cheating on them, they band together to get revenge. It's fun planning their own Home Alone-inspired pranks…until Ellie and Mariah realize they're actually falling for each other.

But the film shoot is too short to get serious, so they'll have to decide: Was their romance simply a holiday fling or a real Christmas-in-July miracle?
