Vengeance. The soldier from Hell.

Years ago, motorcycle stunt woman Kelsey Collins sold her soul to save a life of a loved one. Now, she transforms into a fiery, avenging agent of justice at night wherever evil roams. As the only one who can walk in both worlds, Kelsey is charged by Satan himself to destroy Riser, a demon that wants to overthrow Satan and create a worse Hell then the one that currently exists.
