Stephanie Daley(2007)

The truth is what we believe.

Stephanie collapses in a pool of blood while on a school skiing trip. A doctor discovers that the blood is the after-effects of giving birth. Soon afterward, the body of a newborn baby is found in a toilet, its mouth blocked with toilet paper. Despite Stephanie's insistence that her child was stillborn and that she had no idea that she was pregnant, she is arrested for the murder of the child.
