Rock Bottom?

Odd has a crush on Sam, a rebellious teenager from a neighboring school. They have agreed to meet in secret inside the school grounds at Kadic. Sam leads Odd to believe that he's in for some romance. He quickly comes to his senses when he realizes that Sam is, in fact, planning to steal a laptop computer. Just before being caught red-handed by Jim, Sam manages to hide... and Odd is the one accused of stealing. Jim drags him back to his office, locking all the doors behind him.

While all this has been going on, X.A.N.A's ghost has attacked the foundations of the school buildings, modifying their structure. The foundations crumble, so much so that the school buildings start sinking into the ground like a fleet of shipwrecks.

The only way to avoid catastrophe is to get to Lyoko. But Sam is a prisoner in the science building, which is sinking into the ground.

While Yumi and Jeremy rush to the factory, Odd and Ulrich must do everything that they can to save Sam...
