In Season 2 normalcy seems to be back in Scampia: Maddaloni's gym has reopened and the new club “The Square” has immediately become a hangout for young people, where Pasquale unexpectedly works as a bartender. The memory of his friend Armando still lives in everyone's hearts, especially those of Francesco and Pasquale.
As the Maddaloni clan prepares for Nationals qualifiers, the world of evil reorganizes. Tony Hollywood, now free, adopts a new leadership style, but his past as a pupil of Maddaloni's haunts him; he resents that Francesco chose the master instead of joining him and his brother Ninja. Tensions explode with an ambush gone wrong, forcing Ninja to flee and go into hiding, aided only by his ex Elena, who runs “The Square” on Tony's behalf. To the clan's rescue comes Enzo, a former student and black belt, while Lucia, Ginevra's determined magistrate mother, arrives in Naples. Aurora, a shy and awkward girl, joins the gym, while the boys' personal lives become complicated: Vincenza clashes with an oppressive father; Raffaele abandons judo to devote himself to music, finding love in a secret fan; Gigi and Chantal grow apart.Tony, meanwhile, devises a plan to destroy the clan for good, forcing Francesco to become his accomplice, and keeping him in check with a terrible threat. Francesco will have to betray everything and everyone: will he be able to make the right choice to save himself and protect those he loves?
