Astoria, Queens, is decorated within an inch of its life for the Christmas season, and Mia Carina is juggling her job at the Belle View catering hall with a case of murder . . .
 
Mia’s busy with a full schedule of events at the family business—among them an over-the-top Nativity-themed first birthday party and a Sweet Sixteen for a teen drama queen. But her personal life is even more challenging. Her estranged mother has returned—and her lifelong friend Jamie has discovered a shocking secret about his past. He’s so angry that he starts hanging out with Lorenzo, who claims to be his long-lost brother—even after it becomes clear that Lorenzo’s story is as fake as a plastic Christmas tree.
