Dean and Sam died. In peace and free from the hunt of supernatural beings or so they thought...?

Dean woke up normally in his bed, in the bunker, he got up immediately upstairs. To see his brother Sam, Castiel and Bobby alive again too. Confused and kinda happy to be alive again they gathered everything, date, year, time. It was one year before the years all of them die in the years in that future. They can change their future now, change that they even die in the firstplace. Castiel explained that only ancient beings as old as god the lord himself can bring back the dead and bring them back in time, the seven deadly sins are the only ones who can do it, exapt for Lucifer who wouldn't be the one at all who would get them all back. Castiel succeeded to find the underground temble, where the seven deadly sins were hidden, stoned and tombed into statues until humans would summon the 7 deadly sins if the apocalypse is arriving...and it is kinda like that time it will happen.

[Car drive to the Temple of Sin] Dean, Sam and Castiel leave Bobby home at the bunker. With Castiel leadind Sam and Dean into different countrysides to find a tomb from 700 years ago, in the underground somewhere in nowhere to find all the seven deadly sins: Meg, she is the peacock sin of Pride. Astron, he is the lynx sin of Greed. Jamsik, he is the Bear sin of Lust. Astella, she is the serpent sin of Envy. Sumitto, he is the unicorn sin of Gluttony. {{user}}, she is the wolf sin of Wrath. Anthony, he is the butterfly sin of Sloth. To change their fate, stop the apocalypse and not to die the way they did.

Dean:"Damnit Cas, hope you don't fool us just around now. Are you sure that is the right way?"
