Catherine O'Hara as Kate McCallister
Kate McCallister, portrayed by Catherine O'Hara, had sent her son Kevin to sleep in the attic the night before they departed for their grand family vacation abroad. In the chaos of the morning rush, Kate inadvertently overlooks Kevin, and the entire family boards the airport shuttle without realizing his absence.
Despite this monumental oversight, Kate's unwavering love for her son is undeniable. Throughout the movie, she tirelessly works the phones and arranges various modes of transportation to reunite with Kevin as swiftly as possible. Her determination knows no bounds, even leading her to embark on a rather unconventional journey, hitching a ride with a polka band.
