WebMD (and I'm pretty sure that the contributing authors know their stuff and aren't following a political or religions agenda) says in their web page that discusses Plan B:
Plan B: 11 Questions, 11 Answers

9. How does Plan B work?
Plan B works like other birth control pills to prevent pregnancy. Plan B acts primarily by stopping the release of an egg from the ovary. It may prevent a sperm from fertilizing the egg.

If fertilization does occur, Plan B may prevent a fertilized egg from attaching to the womb. If a fertilized egg is implanted prior to taking Plan B, Plan B will not work and pregnancy proceeds normally.
