De hombre a hombre (1985)

Widower, old retired Literature teacher, Silvestre Sanchís is taken by his son and his daughter-in-law to a nursing home where he fears losing what he loves most: his freedom; for this reason he flees taking advantage of an oversight of his relatives. On the other hand, Carlitos, son of divorced parents, sees himself as an obstacle in their life, so he resolves to escape from home. The old man and the kid live as stowaways in the huge basements of a department store, until one day they meet by chance.
