Isabel is a college student who finds herself descending into depression. She used to find respite on her walks on the beach, but soon her time spent near the ocean brings up a hidden current of dark, forgotten memories from her past. When she drops out of school, her life as she knew it dissolves before her eyes. Unable to lift herself out of her own swirling emotions, she uncovers unexpected anxieties and anger through therapy. She also finds more clues to her past through a source she hesitates to trust: her drug addicted sister. Now as more light falls upon her vague memories, she must make the decision to either struggle to remember everything that happened to her in detail, or find closure in the possibility that she can surface from a sea of depression and anxiety without ever knowing exactly what happened.
