Melanie Parker (Michelle Pfeiffer) is a career-minded architect/Super Mom, taking on the demands of single parenting in New York City. Jack Taylor (George Clooney) is a hard-driving newspaper columnist/every-other-weekend Dad, challenging the improprieties of City Hall. Having been let down in the past, Melanie has almost given up on men, except for the adorable five-year old who calls her Mommy; and Jack thinks that women are just fine...as long as they keep their emotional distance. When they are inadvertently thrown together for one chaotic day, the only thing they have in common are identical cellular phones. But the next thing they know, they're falling in love.
