Shortly after an air traffic controller at the Los Angeles Airport spots a mysterious blip on his radar screen, several residents of a luxury apartment building, known as the Whitman Tower, are startled by the appearence of a UFO outside their windows. Ryan and Fitz fly to Los Angeles to question the witnesses and ascertain the facts in the case. One of the witnesses, Mr. Rashoon, reports he saw only some red beams of light. The other residents, a family named Ryerson, give a more detailed description of what they saw. Their version includes the sighting of 2 beings with horse-shaped heads and medallions around their necks bearing horse images. Ryan and Fitz next head to San Pedro to search for additional witnesses and try and separate fact from fiction in this bizarre case.
