Alex grew up in an orphanage. Six years ago, she had a one-night stand and became a single mom. Now broke and desperate, she chops off her hair, throws on a man's suit, and lands a job as a live-in nanny at a billionaire's estate. To keep her paycheck and raise her son, she fights to hide her true identity—causing one hilarious disaster after another. Then she finds out her cold, gorgeous boss is actually her kid's father. And he starts falling for "him." This time, love begins with a case of mistaken identity, but ends with the warmest happily-ever-after.
