How far would you go to keep a secret? it has been ten years
since Mack went missing. A Columbia University student, he walked
out of his room and has not been seen since. Every year he calls
his mother on her birthday, on his birthday, and on Mother's
Day. He assures her he is fine, then hangs up. Even the death of
his father on 9/11 does not bring him home. Mack's sister,
Caroline, has now endured two family tragedies. Determined to
solve the mystery surrounding her brother's disappearance, she
sets out to discover the truth. But with it comes a secret that
someone will do anything to protect, leading her to a deadly
confrontation with an unexpected enemy.
