The Back-up Plan is a comedy that explores dating, love, marriage and family "in reverse." After years of dating, Zoe (Jennifer Lopez) has decided waiting for the right one is taking too long. Determined to become a mother, she commits to a plan, makes an appointment and decides to go it alone. That same day, Zoe meets Stan (Alex O'Loughlin) -- a man with real possibilities. Trying to nurture a budding relationship and hide the early signs of pregnancy becomes a comedy of errors for Zoe and creates confusing signals for Stan. Anyone can fall in love, get married and have a baby but doing it backwards in hyper-drive is the real pregnancy test.
