One Fine Day

Melanie Parker is an architect and divorced mother to her son, Sammy. Her day gets off to a bad start when she is late to drop him off at school, due to the forgetfulness of fellow divorced father Jack Taylor, a New York Daily News reporter whose daughter, Maggie, is thrust into his care that morning by his ex-wife who leaves to go on her honeymoon with her new husband. The children arrive just a moment too late to go on a school field trip (a Circle Line boat cruise). Their parents are forced to accept that, on top of hectically busy schedules, they must work together that day to supervise each other's child. In their confusion of sharing a taxi, they accidentally switch cell phones, causing each of them, all morning, to receive calls intended for the other one, which they then have to relay to the right person.
