“The Bridge” is not a tidy little connection between two points, or even two sides of a story. It stretches and bends, bringing in new characters before you've gotten to know the older ones, spreading its narrative from police offices and grimy streets to dry stretches of land along the border between Mexico and the United States. Not even the body that begins its story is simple.
Premiering at 9 p.m. Wednesday on FX, the series follows the investigation of that body, left at the midpoint of a bridge between Juarez and El Paso, with part of it resting in the United States and part in Mexico — bringing in law enforcement from both sides. From Mexico comes detective Marco Ruiz (Demian Bichir), an honorable man trying to keep his job (and his life) while working among the cartels and their corrupt associates, some of whom are his co-workers. From the U.S. is Sonya Cross (Diane Kruger), an El Paso detective whose personal challenges include having Asperger's syndrome. Each has rules, though not the same ones.
