Jackson is very lonely when his family has to move to Canada, but what makes it even worse is Jackson's older sister, Lisa.
When Jackson makes a new friend named Chris, both Chris and Jackson figure out that a Witch lives in Jackson's new house! Jackson has to get enough evidence to show his mom that a Witch lives in their house. Since Lisa is cursed by the Witch, Jackson and Chris have to use both of their brain-power combined to exterminate the Witch out of his house.
