The kids and Rubik go on a school camping trip. Lisa doesn't care much to rough it, Rubik just likes hot dogs roasted over an open fire, and Carlos is all about pulling scary pranks on his brother and sister in the middle of the night. In the process, he and Rubik discover that a couple of shady characters are up to some spooky business in a nearby graveyard. Reynaldo and Lisa join Carlos in solving the mystery, by tracking down the shifty thieves and discovering what's in the coffin they dug up.
