A powerful Argentine gangster uses everything in his power to stop the woman that wants to kill him, a sexy mercenary known as "the machine gun woman". The staggering sum of cash he offers for her head sets in motion an army of hitmen. And also, by accident, bursts in the life of naïve DJ Santiago, a common youth that will have to steel his guts against the underworld, and above all, survive the irresistible - and bloodthirsty - Machine Gun Woman.
