How does an insecure teenager become more self-assertive? That's the challenge for Olympia, a young girl stigmatized for being different.
Same Sex Parents begins with Olympia and her classmate Leo enjoying their first romantic encounter at a weekend dance. At school the following Monday, Geraldine, a jealous rival, publicly outs Olympia’s mother. Olympia is shocked, as her mother, Martine, has never actually admitted being a lesbian. Olympia confronts her mother with questions about Olympia's father, who is now openly gay, but Martine is dismissive; in her world it’s never quite the right time to speak about such matters with her daughter.
Sensing a deception and fed up with "issues" surrounding her mother’s sexuality, Olympia turns to her father in Paris. After voicing her distress, she returns home only to find her mother making love with another woman. Her mother’s indiscretion, her tenuous situation at school, and her troubled relationship with Leo all drive Olympia to desperate measures.
