When Catherine notices her seemingly perfect biology professor husband David spends exactly one hour in the bathroom every day, her surgeon best friend Emma stumbles onto his brutal underground experimentation lab. To protect Catherine and her young daughter Lily, Emma throws herself off a bridge, clutching a rabbit sticker as her final clue.
Catherine teams up with Detective Blake, acts as bait, and secretly records David’s full confession of torture, blackmail and attempted murder. SWAT raids the hidden bunker; David is jailed for life. The rabbit sticker remains a quiet, enduring symbol of women saving one another.
