Single mother Alice (Emily Beecham) is a dedicated senior scientist who has just developed a special species of flower that can make people happy. When she takes a flower home to her son, she realises that it may not be as harmless as she initially thought. A chilling drama about the genetic manipulation of plants, ambiguously perched between sci-fi, paranoia and realism that won Emily Beecham the Best Actress Prize in Cannes in 2019.

Followed by a Q&A with screenwriter Géraldine Bajard.
