Heya! Good to see a moderate amount of activity on these forums!
Recently I started a thread over on a 40k RP forum to find new adventure hooks. The mechanic of it worked well so I thought Id bring it over here. Basically you post episode lists of sci-fi/fantasy series and everyone writes the "planescape version" of certain episodes.
Hercules: The Legendary Journeys

Supernatural
Dead in the Water
Taking a break from the search for their father, Sam and Dean head to Lake Manitoc in Wisconsin for a possible case. Three drownings have occurred there within a year, with the dead bodies mysteriously disappearing in the lake. The brothers soon come to believe that the spirit of a young boy haunts the lake, and learn that the local sheriff (Daniel Hugh Kelly) and the father of the latest victim accidentally caused his death when they were children. Out for revenge, the spirit targets the sheriff's daughter Andrea (Amy Acker) and mute grandson Lucas (Nico McEown). It eventually pulls Lucas into the lake, so the sheriff gives himself over to the spirit, saving his grandson.
Planescape
Something in the Air
Taking a break from their journey throughout the planes, the adventurers hear of a series of mysterious deaths while in Sigil. People have dropped dead from suffocation, leading the populous to believe that something is wrong with Sigil's air supply. The adventurers soon discover however that something haunts the inner void within Sigil's "ring," a child slain by a veteran Harmonium officer years ago. The creature it has become is highly resistant to damage and detection and is able to corrupt Sigil's air from great distances. Unless it is appeased or destroyed access to certain portals, mostly concerning the plane of air, will be prohibited for general use.
