Romeo & Joule-watt - S1.E24

Sam's report for school is destroyed by Elizabeth, who draws pictures all over it, and Sam feels he is about to face impending doom at school because of this. But that is the least of his worries when Kilokahn, against Malcolm's wishes, releases a mega-virus monster to sound off an alarm system which will apparently trigger warheads throughout the globe. It's up to Sam once again to save the world from certain danger!
