One night, 19-year-old Sami secretly takes his father's taxi to go to a party, when a mysterious young woman jumps in. They end up at her place and have a wild time together. However, when the day breaks, Sami's life changes forever.

While waiting for his trial, Sami discovers the cruel world of the prison. At the same time, as the police investigation continues, Sami's parents get a terrible shock when they realise how much they didn't know about their son.

Jeff's investigation sheds new light on the mysterious personality of Gloria. At the same time, Isabelle joins forces with Leila, and together they move mountains to defend Sami, who sinks deeper and deeper into desperation.

When another lead reaches a dead-end, Isabelle begins to doubt Sami's innocence. As for Sami himself, he has now become Anis' number one drug dealer inside the prison and is looking nothing like the promising student he once was.

The trial commences at Assizes, but Sami looks anything but innocent in his current state and is strung out on drugs. Isabelle and Leila's hard work on the first day might go to waste.

Two days before the end of the trial, Jeff has second thoughts. At once, he sets again to digging into Gloria's past and what he finds goes beyond all expectations.
