His situation becomes even more complicated when, by mistake, he is unjustly condemned for the crime of drug trafficking in Taubaté, in the interior of São Paulo.

The first, convicted of murder, believes in his lies, which leads him to become his friend and personal security guard, risking his own life to protect the 'Doctor of Traffic'.

The penitentiary is under the command of the director Demosthenes (Adriano Garib), an ambitious and corrupt man who transforms the life of Cadu into a hell.

Meanwhile, his wife Malu (Julia Ianina), willing to do anything to save her husband, enters the charade of Cadu's new identity and becomes the 'first lady' of drug trafficking.

The case of Cadu is still investigated by Jonas (Caio Junqueira), a federal police officer who has been working for years to raise evidence against the Santa Cruz de La Sierra Cartel.
