My Mummy Baby and His Pharaoh Daddy follows museum cleaner Grace, who accidentally awakens tiny mummy Remy after murmuring she wants a child. The little mummy wields ancient golden magic and opens a sand gate leading to an Egyptian pyramid, where the long-slumbering Pharaoh Khai rests. Bound by a three-thousand-year-old pact, the two immortals will gradually turn to stone without Grace’s genuine familial love. Remy acts as a matchmaker to bring Grace and Khai together. The trio hides from museum staff, overcomes life-or-death crises caused by the petrification curse, and learns the true meaning of the ancient covenant. After countless warm, bittersweet twists, they break the death oath and build a permanent warm family in the human world for a happy ending.
