Melanie Parker is a career-minded architect/Super Mom, taking on the demands of single parenting in New York City. Meanwhile, Jack Taylor is a hard-driving newspaper columnist/every-other-weekend Dad, challenging the improprieties of City Hall. Having been let down in the past, she has almost given up on men, except for the adorable five-year old who calls her Mommy; and he 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. The last thing they need is to get involved with each other's lives, jobs and kids. The last thing they expect is to feel an attraction. But the next thing they know, they're falling in love.
