Watch HBO's Nuclear Family docuseries trailer exploring a pioneering gay family

Filmmaker Ry Russo-Young turns the camera on her own past, growing up with her sister and two lesbian moms in the late 1970s and early 1980s. "Ry’s idyllic childhood was threatened by an unexpected lawsuit which sent shockwaves through her family’s lives and continues to reverberate today," says HBO of the three-part docuseries premiering Sept. 26.
