Manic -- Film Description:
"Her brother and sister have hard-to-manage mental illnesses, and it's probably not a coincidence. To uncover the roots of the issues that run in the family, filmmaker Kalina Bertin spent more than four years investigating her own father. More than just remembered images and feelings, she dug into her family's personal archives hoping to understand her loved ones' illness, with the ultimate goal of helping them heal. The result is a portrait of a deeply complex man, a master manipulator and compulsive liar who became a cult leader—a charming con man who fathered at least 15 children."
