I saw this movie on Lifetime TV channel probably between roughly 2008 and 2013. The pedophile father forces his young daughter to masturbate him probably until she leaves home to go to college to become a lawyer. I think her mother knew about it, but did nothing to stop it. Years later the mother regrets not doing anything about it. To do her daughter vigilante justice she plans her pedophile husband death. The mother goes into the cellar and saws the living room floorboards half way through underneath. When her pedophile husband returns home from work, she beckons to him on the other side of the living room. As he walks across the living room floor, the half way sawed boards gives way and he falls through them into the cellar and is killed from the fall. The mother calls the police and report it as an accident. The police gathers evidence and piece together that the accident was staged and that the living room floorboards was tampered with. They charged the mother with murder. The mother then calls her lawyer daughter who now lives in another city. The daughter reluctantly returns. They finally talk about the forced incest and the relationship is somewhat repaired. The daughter being very good at what she does and defends her mother in court. Even though there is proof that the mom did it, the daughter proves that there is not enough evidence to convict her mother and she is found innocent and goes free. During the trail, the daughter did unfortunately have flashbacks of her sexual abuse. If anyone knows the name of this Lifetime movie, please let me know. Thanks you very much for your help.
