Fez dreads impending graduation as he probably must return to his lizard-infested country afterward, so he gets Kelso and Hyde to observe a truce in their Jacky-war to join both on a camping trip by the lake with the whole gang, plus Eric's stupid sister Laurie. Kitty is on heavy tranquilizers as she can't handle her 'baby boy' moving out. After a failed ghost prank by the campfire Eric was to skinny-dip with Donna, but ends up screaming butt-naked with Laurie, who next does it in Kelso's van with Fez, who gets even more out of it then sex... Kelso and Hyde's rivalry for Jackie comes to a near fistfight, until she calls out that "it's no fun for me anymore!" The pair realizes that she's been playing them against each other as revenge for their awful treatment of her over the years, and they demand she finally chooses. Next morning they all oversleep and the van is stolen, so the parents are terribly disappointed the kids all miss their own graduation ceremony...
