Sisters Ashley, 30, and Megan, 24, say growing up they were sexually abused repeatedly by their step-grandfather, Joseph Palmer, and claim their grandmother, Peggy, knew about the abuse — but did nothing to stop it.

The sisters say they can’t move on until they get an apology from Peggy, who continues to adamantly deny that the abuse ever took place.

Plus, what causes Peggy to storm off stage? And, don’t miss Part 2 tomorrow — will Peggy have a change of heart? This program contains strong sexual content. Viewer discretion advised.
