Pauline, a hardworking janitor and single mother, wants to buy her 8-year-old daughter, Eve, a birthday gift. With little money, she finds a beautiful vintage doll at a flea market. On Eve’s birthday, she’s thrilled with the doll, but Pauline hears a strange crackling sound. Inside a hidden pocket, she finds a note reading, “Happy Birthday, Mommy,” in a child’s handwriting.

Concerned, Pauline returns to the flea market and meets Miriam, the seller. Miriam is emotional upon seeing the note—it was written by her late daughter, who had given her the doll before passing from cancer. The women share a heartfelt conversation, bonding over motherhood and loss.

Days later, Miriam visits Pauline and gives her $3,000 from selling her daughter’s toys, insisting she accept it. Their connection deepens, and Miriam becomes a part of Pauline and Eve’s life. From grief blossoms a friendship that brings healing, love, and hope.
