Belle Gibson achieved Instagram-star status claiming she managed her terminal cancer naturally. Netflix's "Apple Cider Vinegar" revisits her undoing.

Wellness influencer Belle Gibson claimed for years that she had cured her brain cancer through nutrition and holistic medicine, only to have her hoax exposed.

Throughout Apple Cider Vinegar, journalists are investigating Belle. One of them, a journalist named Justin (Mark Coles Smith), learns about Belle from his partner Lucy (Tilda Cobham-Hervey), who takes solace in Belle's feed while she’s undergoing breast cancer treatment—and even decides to pause it altogether and try alternative remedies.
