Pavlov

"I will accept anything that showers me with gifts."
When Sadie Collins stretched out her arms and yelled this "oath" to the universe, something was listening. Soon the materialistic girl "finds" a stunning yet spooky slot machine that starts fulfilling her wishes - and turning her life upside down. Known as "Pavlov," the machine demands allegiance for its magic ... or there will be Hell to pay!
Once Sadie realizes something otherworldly is at play, she seeks the help of a pastor, and a parishioner who had fallen under a similar spell. Will God-given talent and wisdom prevail against demonic trickery?

Well, what does The Book say?
