The Tardis and the Impala

There's strange goings on at the Sunnydale Waterpark. People from all walks of life are disappearing from inside its gates, out from under the noses of the employees. The police have no leads, the manager is stymied, and the park is soon to be closed down if nothing changes...

Rory is jealous. Jealous of the Doctor and the way he commands Amy's attention in a way Rory never can. All Rory has ever wanted is Amy, and yet, now that he has her, he can't help but feel she is farther away than ever. No matter what Rory does, it's never enough to outshine the Doctor, and when the Doctor drags them off to investigate some disappearances at a waterpark in America, Rory knows that this time will be no different.

Sam is ready. Armed with his smooth-talking, fast-chewing brother Dean and a marginally clueless angel, he's ready to hunt down whatever supernatural bastard has been terrorizing the park. Eager to make up for his all-too-recent mistake, Sam is confidant that his and Dean's abilities as hunters (not to mention the aid of a well-meaning angel) will be more than enough to eradicate whatever is making the people go missing.

Worlds collide as Rory and Sam and their companions rush to the waterpark, eager to stop whatever entity is plaguing it. Little do they know, the creature in Sunnydale Waterpark may be too strong for all of them...
