"The Long Road Home" from Otherworld

During a three-month trip across Mexico, a Scottish student named Simon and his friend were returning from a beach party when they accidentally ran over something with their car. They got out and realized it was some kind of large black creature. But as they walked closer and it began to stand up, they realized this creature was unlike anything they had ever seen before... The night only got stranger as they got back in the car and tried to drive back to the hotel along the long dirt road that was supposed to be a shortcut.
