Foster Home Seance

In the late 80's a Foster Home is stricken with tragedy and the children are sent to separate foster homes once the home is shut down. Fast forward 30yrs later a death of one of the Foster Brothers reunites the group back at the very place it all started. Missing the recently deceased foster brother the group decides to contact him through a Seance. Because of lack of spiritual experience the Seance goes horribly wrong and instead they summoned a far worse beast, or did they?
