Four on the Floor 1

July 1, 1981. The Fourth of July weekend is over before it begins for LAPD Detectives Tom Lange and Robert Souza. Four people have been found brutally murdered on Wonderland Avenue in the Hollywood Hills. Another has been left for dead. From the extreme violence of the crime, Lange suspects that someone is sending a message. When a handprint is found near one of the victims, the detectives believe it could be their first big break.
