An imaginary friend

Lily, hidden with her blind grandfather who does not suspect a thing, discovers another intruder there. Angèle. An elderly woman, naked, asleep on the living room sofa next to her grandfather. Suddenly Angèle wakes up, and face to face with Lily, immediately becomes invisible. To prevent Lily from divulging the secret of her invisibility, Angèle offers Lily to take her to her home where she can make her invisible as well.
