Something mysterious and violent is killing the cattle of the North American plains, but what is behind these gruesome attacks: satanic cults, an unknown predator, or something previously unknown to man?

Just miles from the industrial cities of Ohio, there is a bogeyman that has terrified local children for over a century.

Engrained in the history and mythology of India are tales of a ferocious creature, half-man, half-ape. It has been dubbed the monkey-man and headlines across the world have told of the vicious nocturnal attacks that occurred in India's capital, New Delhi. The city's population was gripped with fear of a violent creature described by eyewitnesses as having sharp claws, fangs and dark hair. After three people died and dozens were hospitalized fleeing the creature, 3,000 police officers were tasked with capturing the animal, but came up empty handed. Experts were divided over whether this was a case of mass panic or an unknown primate. Even today, witnesses in other parts of the country continue to report terrifying encounters with a similar beast.

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.

Are big bears are getting more assertive and aggressive? In pre-historic times, giant bears weighed up to a ton and stalked early man. Listen as witnesses describe horrific bear attacks and take a look at unusual bear remains.

Large cats are prowling parts of America and they may have a taste for flesh. Witnesses in New York State say they are seeing big black cats that may be stalking and killing the deer population. However, from the big cat family, only jaguars and leopards appear black and neither species is native to the eastern United States. Is the mind, as skeptics suggest, simply playing tricks? Or could dangerous escaped exotic cats be on the loose? An all star MonsterQuest team of trackers, scientists and technicians deploys the latest in surveillance equipment in search of proof of whatever monster is out there--before it kills.

Recent archaeological evidence suggests that common rats once grew to massive sizes. Are these huge rodents making a comeback? Claims of huge rat sightings are being reported in startling numbers. Animal experts believe that these mutant rodents are getting bigger and bolder. Journey into the sewers with rat experts and meet witnesses who tell of cat-sized rats that have appetites for just about anything--including human flesh!

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.
