Three incredible stories about the untapped power of the human brain: A Los Angeles woman’s paranormal vision leads detectives to a murder victim; a California man remembers every single moment of every day of his life; and, a woman visits a faith healer who miraculously cures her chronic pain.

Three ancient artifacts that could turn the history of the world upside down: In Mexico, a bizarrely-shaped skull may prove aliens once walked the planet; ancient stone carvings of dinosaurs could rewrite the story of evolution; and, an ancient wooden model may be proof that ancient Egyptians invented modern flight.

A series of unsolved murders. A cryptic set of clues. A dead end at every corner. The serial killer known as the Zodiac long terrorized the residents of the San Francisco Bay area while taunting police. He was never caught. Now our team of investigators have identified a new suspect, and with the aid of a groundbreaking new DNA technology have the chance to come one step closer to finally solving the mystery of this murderous crime spree.

In one of the earliest documented serial murder cases, five prostitutes in the Whitechapel district of London were found brutally murdered with throats slashed and bodies mutilated. All the deaths were attributed to one man: Jack the Ripper. Never solved, the accepted theory is that the killer was a local madman. Now, 120 years later new evidence indicates two surprising new theories: the killer might have been a woman, or the killer was not English, but American. MysteryQuest's team of experts heads to London to follow these leads and examine the evidence first hand.

Chimpanzees are known to us as amusing circus attractions and are even popular as pets, but when they attack the results are frightening and horrific.

In 2006, The New York Times revealed a sinister plan by Soviet dictator Josef Stalin to create monsters by crossing humans with apes. Travel to Russia to find out if this was true and if so how far did he get?

The werewolf is a centuries-old legend based on myth, not a real animal. However, local eyewitnesses in Wisconsin and Michigan report seeing a dogman--a tall hairy man-beast. Professional hunters and trackers armed with tranquilizer guns will be deployed in an area of recent sightings to find this creature. For the first time polygraphs and hypnosis will be used on eyewitnesses with astonishing results. One-part history, one-part science and one part monster, discover the truth behind legendary monsters.

A deadly, slithering menace is taking over Florida and may be heading north. For more than 100 years, giant pythons have been discovered in parts of the Sunshine State, but since Hurricane Andrew in 1992, their territory has rapidly spread. Now, MonsterQuest searches for incursions in the outskirts of Miami, a population hotspot that is just moments from schools and homes. The team investigates whether pythons could hybridize and adapt, enabling them to threaten every state in the US.
