After four years of unrequited love, Elise survives a terrifying, near-fatal in-flight emergency. Desperately calling her husband Ethan, she hopes he will finally show he cares. Instead, Ethan spends the night comforting his mistress, ignoring Elise's calls and her severely damaged eardrums. After taking 109 lonely flights while he turned a blind eye to her pain, Elise decides her next flight will be her final departure—away from him, forever.
