In the Dark of the Valley (2021)

Plot

In 1959, a partial meltdown at the Santa Susana Field Lab led to a catastrophic radiation leak, widely regarded as the worst nuclear disaster in U.S. history due to its proximity to Los Angeles. For two decades, the incident remained shrouded in secrecy, with lasting environmental contamination. Investigations have since revealed a series of alarming accidents and negligent practices, including the use of open-air burn pits that dispersed radioactive waste across the valley. Today, the site stands as one of the most contaminated locations globally, highlighting the dire consequences of inadequate safety measures in nuclear operations.
