Hache and Juana belong to opposite worlds, but the night that the band "Cumbia Ninja" is born by accident, in the midst of the dangerous neighborhood "La Colina", the fates of Juana and Hache are bound forever.
Hache faces the challenge of becoming leading voice to the music band while Juana seizes a unique opportunity: get back to the crime scene and avenge her family.
Hache feels for the first time that his music has the power to put a stop to the violence among the gangs of his neighborhood. There is much to protect in La Colina, especially Nieves, the new girl in the hood.
While "La Colina" seems reborn thanks to the influence of Hache, Master Xiang Wu risks his life to go into the enemy's den. Nieves attempts to take advantage of Italo's interest to get closer to the truth, and she herself becomes the prey.
When everything seems to go smoothly, Hache makes a mistake that not only puts at stake the future of Cumbia Ninja, but also the confidence and love that Nieves and the people of "La Colina", had bestowed upon their leader.
Hache takes over and gets his sister back, but a dark secret comes to light and his natural ability to be the leader of the neighborhood is very much doubted.
While Cumbia Ninja focus on their music and competes against other bands, the real threat to the secret that lies under the neighborhood reveals itself with a mortal blow that unleashes violence on the streets of "La Colina".
Violence breaks out in La Colina and Leon takes advantage of the chaos to find the secret that could make him a millionaire. But Juana finds the weak spot in what seemed a perfect offensive and launches her plan for revenge.
While the gang "2200" starts the final attack on "La Colina", in the house of Carbajal León organizes a party to divert attention. But things do not go as planned and in the blink of an eye, Cumbia Ninja are on the verge of death.
In front of thousands of viewers who see them live and direct, Cumbia Ninja steals the big night of "The battle of the bands". But peace in "La Colina" once more crashes into pieces.
