Plot
Kate Maclean and Munro Maclean have two twin boys, Andrew and James. One day at school, Andrew has a new classmate named Étienne Blanchard, who looks virtually identical to Andrew and has the same birthday; after medical tests confirm that Étienne and James were switched at the hospital, however, Étienne's mother Marie leaves town rather than complying with the court order to surrender custody of Étienne to the Macleans in exchange for James. This development fractures the Maclean family, as Kate's unrelenting obsession with regaining custody of Étienne destroys her relationships with both Munro and James.Years later following Munro's death, the now adult Andrew and Étienne reunite at his funeral for the first time since the incident; while Andrew has maintained a brotherly bond with James despite their mother's attitude, it too is now tested by Andrew's desire to build a closer relationship with his real twin.
