The Ouija Exorcism(2015)

In 1985, a famous warrior trapped a terrifying demon inside a summoning tablet. They thought it was some kind of game and his son played without obeying the rules and let the devil lose. To save his son, the warrior sent him somewhere far away until the devil could be destroyed. Thirty years later and after his death, his grandson finds this tablet and makes the same mistake as his father. Now the devil is back and roaming the earth. The government pays for the threats and intimidation of those who are responsible for the prison.
