Ten year old Gina dreads Christmas. Living in hiding, orphaned and alone, her mantra is "Never get to know anyone. Always be invisible!" One night, she breaks into an empty house whose residents are on holiday - a perfect place to celebrate Christmas all alone. Everything gets upside down when she discovers a baby dragon in the garage. The neighboring kid, Mortimer (10), is surprised to discover them in the house where he was just supposed to feed a goldfish. Mortimer is hard to find any friends. He decides to deal with his loneliness through social media. Sara and Mortimer are forced to become cooperating buddies to save the baby dragon from the local dragon hunter, the police and TV reporters. They both earn much more during this rescue then they ever hoped for.
