Kim has a secret, but she's not talking. In fact, she's not telling the truth half the time. All we know is that she doesn't seem to understand the customs and culture of the people of Earth in New York City. She has a naive curiosity about even the simplest things like what a Zinfandel is, or why people put sugar in their coffee. Her roommate has never seen any of her friends. She's all alone, but soon she meets others like herself and the truth is gradually revealed.
