But when Chloe is injured by an elderly babysitter who has slipped into dementia, Linda wants to ensure that her child is never hurt again.

As Linda later learns, to her horror, Heather's intentions go far beyond the mischievous.
A hidden camera or spy camera is a camera used to photograph or record subjects, often people, without their knowledge.
