Recovering from her injuries, Lily wraps herself in an opioid cloud. Later, a barely avoided tragedy motivates her to flush the narcotics. But her return to sobriety is overshadowed by unnerving memory lapses and her husband's growing mistrust.

As unremembered events become more disturbing, Lily is convinced that she's being stalked. Though her attacker started the destruction of her life, someone else is determined to finish it.
