Slums of Beverly Hills (1998)

Vivian's family are penniless nomads, moving from one cheap flat to another in Beverly Hills so she and her brothers can attend the city's schools. Uncle Mickey sends them money to survive. When Mickey's daughter Rita runs away from an asylum, Vivian's dad offers shelter to her if Mickey will pay for a plush flat. Vivian must babysit her adult cousin, making sure she gets to nursing school and avoids pills and booze. But Vivian has her own problems: she's curious about sex, likes an older neighbor kid, has inherited her mother's ample breasts, and wants a family that doesn't embarrass her. Can she help Rita, keep Uncle Mickey happy, and feel OK about her body and her family?
