In the quiet suburb of Cheshire, Connecticut, Jennifer Petit and her two young daughters were killed in a horrific home invasion; husband and father William Petit was the only one who escaped alive. This gripping film explores the events of that shocking triple homicide that rocked the town and set off a politically charged death-penalty trial. The result is a disturbing revelation of police failures and untold personal dramas that point out the biggest tragedy of all: the crime could have been prevented at many turns.—Anonymous
