Nia, a timid and constantly bullied girl learns her parents are getting divorced, runs away and gets into an accident that puts her in a coma. Nia wakes up in Amygdaland as her favorite superhero, Warrior Queen.
Amygdaland is ruled by Dark Queen. Her Knights; Fear, Doubt and Esteem are her enforcers. Poor people in Amygdaland are forced to work in an internment camp and those who can’t work are killed.
Nia spends her first few minutes in Amygdaland running from them because the myth in the land says that Warrior Queen will save Amygdaland from Dark Queen.
After falling into a well, trying to escape Fear and Doubt, she gets saved by Hope, a little girl who tells her about the myth.
Nia doesn’t believe the story but she follows Hope because she felt lost. Hope takes her to Courage to train her but he doesn’t believe in the Warrior Queen, so he turns them down. But Hope remains, “Hopeful”.
Fear and Doubt send their attack dogs (Beasts of burden) after them. Out of fear, Nia uses her powers to protect herself and Hope but she gets captured by Fear. Hope escapes. Courage witnesses the whole thing and finally believes.
The beasts of burden attack Hope, but Courage saves her. Nia gets taken to the Dark Queen’s castle for interrogation. Esteem realizes she’s weak, so they taunt, torture and send her to the camp to break the prisoners who hoped she’d save them.
Courage and Hope come to her rescue. Fear almost kills Courage but Nia saves him and passes out, giving Hope and Courage time to take her home, where Courage begins her training.
Nia learns that Courage used to be king. Courage tells her that Dark Queen almost got into an accident, so out of fear, she destroyed the car and everything around her, including her parents. Out of guilt, she covers her face with a black veil.
The people waged war against her, forcing her to conjure her knights and soldiers. After winning the war, she took all the hopes and dreams in Amgydaland, turned it into a key and hid it in her chest.
Doubt suspects Nia is in Courage’s mansion, so he goes there with some soldiers. Nia and Courage defeat them and go underground. With a mineral provided by Hope, Courage forges a sword for Nia.
Courage and Nia save the people in the camp, defeat Fear and Esteem. After subduing Dark Queen, Nia figures out she is Dark Queen. She almost had an accident as a kid and her parents blamed each other, starting the fight that would lead to them wanting a divorce. Hope is a younger version of her that used to be positive.
Dark Queen hands Nia the key. The three of them merge and turn into the real Nia. They create a portal and walk through it after saying goodbye to Courage. Everything goes back to normal in Amygdaland. Nia wakes up surrounded by family more confident.
