The story of a group of Catalan children and teenagers who meet as patients in the children's wing of a hospital.

"Under the sofa" is a comedy in which a group of lost objects get a second chance as they live in hiding under a sofa. Part sitcom, part adventure series, in “Under the Sofa” we meet imperfect characters forced to live together in imperfect harmony, trying to survive in the apartment of a family that aspires to perfection.
