After losing her band mate and brother to a drug overdose, rising rock star Hayley (Evan Rachel Wood) finds herself in a downward spiral. The second album from her band Plush is received as a critical and commercial disaster. She finds new hope and friendship in Enzo, the replacement guitarist who inspires her to reach new creative heights. But soon their collaboration crosses the line sexually and Hayley, who is married with two children, retreats from Enzo’s advances. As Hayley slowly discovers Enzo’s dark and troubled history, she realizes she may have let a madman into her home and family and that her mistake may cost the lives of people closest to her.
