Duped into thinking the world is coming to an end, Hank the Cowdog winds up in town for some more adventures including getting in and out of a case of "soap hydrophobia.".
Hank the cowdog and Deputy Drover investigate a monster that appears just as they are about to arrest Eddy the Rac for ripping one of Sally May's sheets while it hangs on the clothesline.
When he gets blamed after one of Eddy the raccoon's tricks backfires, Hank's search for the missing Eddy leads him and his sidekick Drover to a haunted house.
