Babysitter (2004)

Plop, named for the sound he made at birth, is a wanted infant caregiver. Unsuspecting parents, including a proud gay couple, hire the nanny under the belief he provides excellent care for their toddlers. Instead, Plop abuses and humiliates the children, projecting his own emotional problems onto them, stemming from a past relationship. As police close in, Plop's reign of cruelty will soon be brought to an end, possibly by law enforcement or a child in distress.
