When Beth's mother suffers a "mid-life crisis," as Beth puts it, the family leaves their California home to visit the grandparents that they have never met in Philadelphia. Bitterness and anger between Beth's mom and her strange Aunt Iris threaten to tear the house apart and ruin any chance Beth has of having a happy summer vacation. The mysterious circumstances surrounding the death of Clifton Becker twenty years ago have come back to haunt the family, and Beth is determined to find out what happened...even if it means that either Aunt Iris or her mother is a murderer!
