In January 1953, a tidal surge shook the North Sea. The titanic waves flooded the Dutch coastline, killing almost 2,000 people. 54 years later, a similar storm threatened the region. But this time, they were ready. This was thanks to a massive, interlocking system known as the Delta Works— the most sophisticated flood prevention project in the world. Stefan Al dives into this marvel of engineering. [Directed by JodyPrody, narrated by Addison Anderson, music by André Aires / AIM Creative Studios].
