Michelle Rodriguez, Adrian Grenier and Linda Chavez all share Latin-American roots, yet each views identity differently. What does it mean to be Hispanic? The answer lies in the tangled histories of European, Native American and African peoples. Crisscrossing Mexico, Spain, the Caribbean and the Southwest, Dr. Gates reveals stories of ancestral Conquistadors, Indian rebels and "Crypto-Jews" (Spanish Jews who converted to Catholicism to survive the Inquisition, but continued to practice their religion in secret). See how the American experience has been shaped by people who were in the New World long before the Mayflower. 

In what may be the climatic case of his career, Sherlock faces Moriarty's diabolical plot to "get Sherlock," which begins innocently enough when the criminal mastermind breaks into the Crown Jewels.

The demand for better and faster cell phone service comes with a hidden cost. This joint investigation by FRONTLINE and ProPublica has found that the independent contractors who are building and servicing America's cellular infrastructure are 10 times more likely than an average construction worker to die on the job. Complex layers of subcontracting insulate the carriers against liability, despite the fact that they set the aggressive schedule that can force subcontractors to cut corners in order to meet deadlines.

This film investigates the parallel stories of collapsing Pacific salmon populations and how biologists and engineers engage in audacious experiments to shore up their numbers. Each of our efforts to save salmon has involved replacing their natural cycle of reproduction and death with a radically manipulated life history. Our once great runs of salmon are now conceived in laboratories, raised in tanks, driven in trucks and farmed in pens. The program goes beyond the ongoing debate over how to save an endangered species. In its exposure of a wildly creative, hopelessly complex and stunningly expensive approach to managing salmon, the film explores possible paths to salmon recovery.
