Isi and Disi, the two most riotous heavies from the town of Leganes are back. Now, Disi falls in love with Angie, an ex-rock singer and Berdun's girlfriend, a big shot in the music production world. After being named the most brutal band in the no less brutal contest hosted by Angie, not only will Disi have to save his band "Deadrat", his friendship with Isi, and the temple of rock "Hell's Bells", but he'll have to rescue noble Angie from the hands of Machiavellian Berdun. Once more, rock triumphs over evil.
