Heaven's Gate: Amerikánka: What can keep you alive when the whole world is against you and you're still a child? Not much. Ema Černá, the heroine of a story inspired by real events, overcomes the hardships of a children's home, foster care, and juvenile detention on her journey. The most important part of her will to survive is her belief in herself, her belief that somewhere far away, perhaps even in America, there is someone who cares about her.
