In a small town in Wisconsin, Sam and Dean investigate a series of mysterious drownings officially explained as suicides.

Sam and Dean investigate a small town in Wisconsin where children are falling into comas for no apparent reason.

When two highly successful professionals die after claiming to be haunted by hellhounds, Sam and Dean investigate a local bar and discover that it sits upon a site where a deal-making demon has been making people's dreams come true in exchange for their souls. Dean summons the demon to exorcise it but is horrified after it reveals the painful truth about his father's death and tempts Dean by offering him the one thing he wants more than anything--his father.

Sam and Dean investigate a brutal death and discover that the killer is a lycanthrope: a werewolf.

After hearing about a ghost that has been killing off inmates one by one, Sam and Dean decide the best way to investigate is from the inside--so they allow themselves to be thrown into a penitentiary.

While hunting a djinn, or genie, Dean is attacked and transported to an alternate world.
