As Jimena runs for her life, she is caught by the police and placed in a juvenile detention center, where she is further menaced by a trio of mysterious shape-changing sirens. Her only choice is to make a break from jail and hide out with a most unlikely ally - her old gang nemesis, Payasa. Together they must save the other Daughters of the Moon before Jimena's most terrifying premonition comes true.
