Tommy is a twelve-year-old child with an obsession, taking his cat Milo to his sisters: Tara, who was adopted by a neighbor, and Polly, who lives on the street. But his plan gets ruined when his mother, a nurse, disappears into thin air after kidnapping a newborn baby from the hospital where she worked. The police search their home and the truth slowly comes to light: this woman was not their real mother; both Tommy and his sister Rebecca were kidnapped when they were young. Tommy is forced to leave Milo with a neighbor and he is placed in an institution, waiting for his real parents to be found. The child falls into depression, but regardless of everything that happened, he maintains a deep connection to the memory of his cat. When the parents are found, Tommy, instead of going home with them, runs away. But when he goes to the neighbor to take back Milo, both he and his sisters have disappeared. The only solution Tommy sees is to get help from a very strange private investigator, Vera Masala, hoping to find them again. The encounter with this odd woman and her companion Sara will change Tommy’s life forever.
