In the late '20s, gangland killings were tearing Chicago apart, as mob leader Al Capone battled to be top dog. Valentine's Day 1929 was be a bad day to be in Chicago if you worked for the competition. Newly elected President Herbert Hoover was outraged, and declared a war on crime in his inaugural speech. Within months, an elite squad of federal investigators called the Capone Squad, AKA the Untouchables, hit the streets of Chicago. The man in charge was the hard-driving, bright-eyed, and squeaky clean 26 year old, Eliot Ness. Capone's path was clear. He was going straight to hell. But Ness's path took a series of unexpected turns. The man who could track down bad guys with ease, wouldn't always detect the secret malice in people's hearts.
