1x5 - The Unexplained Files

There are many areas around the world where rainwater has turned a disturbing shade of red. The most mysterious rain of all is the Blood Red Rains of Kerala, India. Could this mysterious rain be carrying alien life? If so, how does it arrive on Earth? Carolina Beach Boom- Residents of a beach town in South Carolina experience a mysterious boom that rumbles the ground around them and shakes the glass on their windows, sometimes on a weekly basis. Locals speculate that it could be because of alien involvement or secret military tests, but no one has been able to get to the bottom of these strange events.
