SUPERNATURAL : Blood Oath

The story of Sam and Dean Winchester is one of legendary proportions. Their travels across the country have taken them to the darkest corners of the supernatural world, facing off against everything from demons to angels and even gods.
When Sam receives a mysterious message on his phone about the possible return of the fabled Angel Tablet, the Winchester brothers know that they must investigate. What they find is far more sinister than they could have ever imagined.
Their investigation leads them to a parallel universe, one that is eerily similar to their own but with some striking differences. Here, they meet two brothers named Stefan and Damon Salvatore, who happen to be vampires. While initially wary of each other, the four soon realize that they share a common enemy: a demonic god named Malphas.
Malphas is unlike any other monster they've faced before. He is a powerful being who threatens not just one universe, but both. Sam, Dean, Stefan, and Damon must work together to stop him before it's too late.
The stakes are high, and failure is not an option. It's a race against time to stop Malphas and save both universes from destruction.
