Ep 15. Holiday In the Fog

Jeremy manages to get himself grounded for the whole school holiday period. He wants to be there in case X.A.N.A, the super-calculator, should decide to launch an attack over the break. Sissi, who suspects Jeremy has secret activities, works things out so that she is also at school during the holidays. The Headmaster has put Jim in charge of watching over the two young people. Jeremy's fears are confirmed when X.A.N.A succeeds in spreading highly-toxic fumes throughout the school, posing a direct threat to Jim and Sissi who are holed-up in a tiny little room. Jeremy must face the X.A.N.A all by himself, so let's just say that it's a hopeless situation. He calls Yumi, Odd and Ulrich to the rescue. Will they get back to school in time to lend him a helping hand?
