To free themselves from Hell, several demons have scattered across the universe looking for seven keys with the ability to free them or to kill them. After thousands of years the demons have been able to find 6 of the 7 keys, and unfortunately for mankind that seventh key resides on Earth, protected by a guardian who may use blood contained in the key to harm demons.
The current protector is Frank Brayker, a person who received the key during world war one by a fellow soldier named Dickerson.
After a dangerous high speed chase with a demon known as The Collector, Frank rests at a hotel. Soon the whole night becomes a heavy battle for the fate of the universe.
