Home Alone 3 is a 1997 American family comedy film directed by Raja Gosnell in his directorial debut, written and co-produced by John Hughes, and starring Alex D. Linz and Haviland Morris. A standalone sequel to Home Alone 2: Lost in New York (1992), it follows Alex Pruitt, an 8-year-old boy who defends his home from a dangerous band of international criminals working for a terrorist organization. It is the third film in the Home Alone franchise, and the first not to feature actor Macaulay Culkin, director Chris Columbus, or composer John Williams; Gosnell had previously served as editor on the first two Home Alone films. It is also the final film in the Home Alone franchise to receive a theatrical release.

Plot

Peter Beaupre, Alice Ribbons, Burton Jernigan, and Earl Unger are four internationally wanted criminals who work for a Hong Kong-based terrorist organization. In Silicon Valley, California, they steal a $10 million missile-cloaking microchip and hide it inside a remote control toy car to sneak it past security at San Francisco International Airport. However, a luggage mix-up causes a Chicago-bound elderly passenger named Mrs. Hess to inadvertently take the thieves' bag containing the car. The thieves arrive in Chicago and systematically search every house in Hess's suburban neighborhood to find the chip.
