During a house party Isy is ganged raped. She has no recollection of the crime. Her best friend Jonas is one of the perpetrators, but he is keeping silent about what he did.
The 16-year-old teen Jonas is in love with his best friend Isy, but she likes older boys. When Isy takes drugs at the party and loses control while intoxicated, Jonas and his friends Lenny and Martin first make fun of it. But the situation escalates and the three teens rape the unconscious girl.
Since Isy can't remember anything, the crime will apparently go unpunished. How will things unfold if no one talks?
"ALL ISY" tells an agonizing tale of sexual violence - and of possible forms of intervention. An important film and disturbing film." (sueddeutsche)
