There's taped conversations between the father and step-father where the father lays out his entire plan.
“And if I go through with this, I win big-time. There’s no way I lose. I’ve checked that inside out. I will get everything I want, and they will be destroyed forever. June will lose [custody of the son]…and Michael’s career will be over.”
