The latest trailer for Season 4 of The Walking Dead hints that a new female character will be introduced to the show. The voice is somewhat similar to Lauren Cohan's Maggie, but it does sound a bit different, and we don't actually see who says "Please help me." What help does this mystery woman need from Rick (Andrew Lincoln) and his group of survivors at the prison? Take a look at this footage, then let us know what you think it may mean for the survivors of the hit AMC series. The season premiere "30 Days Without an Incident" airs Sunday, October 13 at 9 PM ET.
