In the movie Hell and Back we see a group of three friends who are going to be in trouble. One of the friends ends up in hell accidentally, so the other two have to design a rescue plan.
As they travel to hell to bring their friend to our world they meet with Deema. She is a strange being, a mixture of woman and demon that thanks to that mixture of races can move both for our world and for hell.
Maybe she is the only one who can help them, but she is an independent and very rebellious woman, so having her is going to be very complicated, which will despair the two friends, who only see her as a devil.
At first glance it seems like one more devil, but as we have said before it is half human, something friends do not know and she is not going to tell them, or at least not at first.
