February 1971 On the morning of the devastating Sylmar Earthquake, pop sensation Vicki La Monica is found dead. Police want to close the case quickly, calling it a drug overdose. After all, it has only been weeks since the famous drug-deaths of Jimi Hendrix and Janis Joplin. Vicki's father won't buy it. Chuck Donnegan, a retired LAPD homicide detective, knows his daughter would never take drugs. He dives into the ultra-hip world of the seventies music scene to prove it. Out of place, physically and emotionally exhausted, Chuck's public criticism of the police causes the media to focus on him. They brand him The Vigilante Dad, follow him everywhere and train cameras on his every move. And now someone wants him dead.
