Angela (Heather Graham) and Curtis (Jerry O'Connell) have it all - a loving relationship, a beautiful house and successful careers. That is, until an unexpected pregnancy sends them on a nine-month roller coaster ride. Now, they must deal with jealousy and suspicion, Angela's over-demanding boss (Lara Flynn Boyle), plus all the drama caused by their "happily" married best friends Danny (John Corbett) and Sylvie (Katie Finneran). It all adds up to an uproarious battle of the sexes.
