Producer-screenwriter John Hughes scores the "Home Alone" hat trick with this second sequel to the slapstick blockbuster, which now finds savvy school-ager Alex under siege by spies while quarantined at home with the chickenpox. Due to an airport mix-up, the spies' super-secret computer chip finds its way to Alex's quiet, tree-lined street, and only he can prevent its rightful owners from ransacking his house.
