Although Apple Cider Vinegar closely follows Belle Gibson's rise to fame, the lines between truth and fiction is blurred in the Netflix series.

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.
