Starting in the 1950s, Cadillac Road is the story of Sharon
Desjardins: from her earliest childhood memories leaving Northern Quebec
and a violent father to adventures in Buffalo and Crystal Beach with her
mother and younger sister, Gloria, to dreams of escaping claustrophobic
poverty in shabby Grenville by going to Toronto and marrying a wealthy
lawyer whom she doesn't love, having turned down local boy Clinton
McClary because she doesn't think he'll amount to much. In the end,
depressed and on pills, Sharon realizes she needs to be true to her
heart, abandons her marriage and takes to the road, a road that could
very well lead back to her original hometown of Cadillac.
