Interchange, a story that focuses on life, death and choice, draws together the lives of five seemingly disparate characters: A hard-driving businessman struggling to raise his grandson. A paroled convict hoping to find redemption. A shy college professor trying to win the approval of his students. A middle-aged office manager pressured to hide her secrets. And a haunted young man hungry for revenge. As their stories unfold in plots both tragic and comic, these desperate souls find themselves intertwined in each others' battles and dreams.
