Both movies are about a girl being kidnapped in the middle of the street, and the horrible experience she goes through in the mental hospital. A producer in both movies covers and brings her story to the light for the world to know.
Nothing is different as both are similar from the plot, characters whether the ones that had a lot of screen time or minimal, revenge goal, and many similar things. However, it’s noticeable that compared to the Korean movie, here Robert Knepper, or known for his role as T-Bag, plays a role in this one, as the villain.
