Bernard thought he was an only child. One day he learns the shocking truth: he is just one of a number of clones. Together, he and his father confront epic questions of identity, intimacy and belonging. A Number pushes the boundaries of science and ethics with an astonishing twist on the dynamics of the father/son relationship.
