An American nanny is shocked that her new English family's boy is actually a life-sized doll. After she violates a list of strict rules, disturbing events make her believe that the doll is really alive.
 
FUN FACT:  Cast members actually used the doll ("Brahms") to prank each other on the set. On one occasion, one of the cast members propped the doll up outside of the other actor's bathroom in their trailer to scare them. Upon seeing this, they hurled the doll outside of their trailer and the crew had to repair it and make a replacement doll.
