Sounds like my last stay at the Motel 6...
"Welcome to Motel Hell.
Nine of the most notorious and violent serial killers are scheduled for a simultaneous execution.
As the nine killers stand on the gallows, spectators recount the horrific atrocities and unbelievably gruesome murders committed by each condemned killer. There is comfort in the belief that not just one, but all of these killers will soon be executed and banished into the depths of hell.
Wait, just as the execution is about to take place, the earth opens up and swallows all of the condemned, along with their appointed executioner, the warden.
In present day, the warden is now the manager of a small motel, the Motel Hell.
On a dark and rainy night, guests begin to arrive and check into rooms at the Motel Hell. The guests range from a prostitute and her client to drug dealers to gang members to a serial killer.
As guests settle into their rooms and begin their own atrocities, they discover the horror that each motel room is connected to hell, allowing the nine killers to rise from the depths of hell and continue their carnage.
Welcome to horror.
This script takes nine of the most violent killers and puts them into one location. It is horror confined."
