Split (Sidestreets)

After her mother suddenly leaves her family for good, Sandra is left behind with her alcoholic father -- and a lot of anger. At first, Sandra is more concerned with getting a job and getting on with her life, but then the people around her start pushing Sandra to at least try to find her missing mother. What will Sandra say to her mother if they are reunited? And how do you find a person who may not want to be found?
