One Crazy Mission (PZPTH/ SPN/ SD Xover)

Sam and Dean Winchester, along with their good friend Castiel, head over to Middleburg after the angel tells them that there's something big in that town. Upon arriving, they come across the abandoned Odyssey theater, where they meet the part time heroes and learn about the multiverse.

However, when the Scooby Doo gang show up thanks to the MTP, Team Free Will And the Part Time Heroes have to work together to not only set things back to normal, but also get the multiverse back in balance as well. Sounds simple enough, right?

Well, not so much.
