Beverly Hills, 90210 - Season 1 Episode 14

The Walshes allow a young Latino girl named Karla Montez, (their maid Anna's niece) to use their address so she can attend West Beverly High School. Brandon becomes intrigued with Karla, but he suspects that she's hiding something due to her wariness and a strange man following her around. Later, when Jim arranges a party for one of his clients, Brandon causes a scene when he finds Karla at the party serving drinks and thinks she's being used as cheap labor.
