Kept and Dreamless (2005)

Florencia, a young irresponsible mother and and her precocious daughter, Eugenia, have an unusual relationship. The roles between the two are reversed: drug-addict and unemployed Florencia is totally inept at caring for a daughter, whereas Eugenia, with only 10 years old, shows a degree of maturity and responsibility far beyond what her age might lead people to suppose. When Florencia gets pregnant again, their relationship, way of life and whole world will change forever.
