In the world of Gattaca , society is divided into "Valids" (genetically engineered) and "In-Valids" (conceived naturally). This system replaces traditional forms of prejudice with a data-driven "genetic ghetto." The protagonist, Vincent Freeman, represents the "In-Valid" underdog who must become a "borrowed ladder"—using the genetic identity of a paralyzed Valid, Jerome Morrow—to fulfill his dream of space travel.
