An arsonist has been at work in San Francisco, setting so far two house fires in three weeks. The two sets of residents - both families - all perished, except for one person. Unlike the work of most serial arsonists, these fires were meant to kill their inhabitants. Before she dies, the sole survivor of the those two initial fires tells Hotch and Prentiss of irregularities from that evening before and during the fire: that someone had turned off the water, that the smoke alarms did not work during the fire, that someone had locked the front door in such a way that they could not escape, and that she noticed a fireman inside the house just before she passed out. That fireman they know to be the unsub. Beyond general characteristics, Garcia finds one connection between the two families: the father figures both worked for different companies accused of LUST (leaking underground storage tanks) by an environmental activist/eco-terrorist (depending on one's viewpoint) group called the Earth...
Did You Know?
The Earth Defense Front (EDF) in this episode has a similar name to the real-life group Earth Liberation Front (ELF). The ELF are radical environmentalists who have been involved in arson and other property damage. The FBI considers them to be "eco-terrorists." See more
At the beginning of the episode, the home is identified as being located in South San Francisco. South San Francisco is not part of San Francisco; it is an incorporated city in San Mateo County that doesn't even share a border with San Francisco, which is a consolidated city and county. Yet the police officers who respond to the crime scene belong to the San Francisco Police Department. Why would SFPD respond to a crime outside of its own city--and in a completely different county? South San Francisco Police or San Mateo Sheriffs should respond.
Later in the show, the suspect is in the "harbor area." San Francisco does have docks along its northeastern and eastern shores, but the area pictured does not look like anything in San Francisco. The only comparable area, the old Hunters Point shipyard, is largely closed off to the public, and the buildings in the show don't resemble anything in Hunters Point. See more
