Girl Inside -- Film Description:
"A moving and intimate portrait of 26-year-old Madison as she transitions over three years from male to female, tracking her emotional, spiritual and physical journey of self-discovery. Advising her on all things feminine is Madison's glamorous 80-year-old grandmother, Vivien—with at times hilarious results—resulting in two vastly different experiences of womanhood. A thoughtful exploration of gender, femininity and sexuality."
