Valentine's Day 1929 marks the most infamous gangster mass murder in history, when warring mobsters Al Capone, "Bugs" Moran, and others fought for their share of the profits from illegal booze, brothels, and gambling in Chicago.

It's 1929, and inside a garage in downtown Chicago, host Theo Wilson witnesses the bloodiest execution in gangland history--the St. Valentine's Day Massacre. But how did Al Capone and a Northside/Southside battle triggered by Americans' thirst for booze get us here?

St. Valentine's Day, 1929. While many Chicagoans enjoyed a romantic evening, a brutal scene ensued at SMC Cartage Company Garage. Al Capone, in a bitter feud with rival George "Bugs" Moran, ordered the death of seven members of Moran's gang. We examine technology of the day that eventually helped bring Capone to his knees--like the speed graphic camera that photographed the bloody aftermath and printing presses that reproduced it nationwide. And we look at Calvin Goddard's pioneering forensic work.

The estranged wife of a millionaire is found with her throat cut. A home burglary goes terribly wrong, and the occupants are gunned down. These may sound like crimes from today's headlines, but they actually date back nearly a century. They are forensic firsts, the true crimes that helped inspire two of today's most indispensable investigative tools: trace (microscopic) evidence and ballistics. We also follow the career of Calvin Goddard, the investigator who solved the St. Valentine's Day Massacre.

Chicago was once a playground for mobsters and corrupt politicians. It wouldn't be the third largest city in the U.S. today if it weren't for the shady dealings that went on just beneath its streets. From vice dens and top-secret railroad lines to sunken shipwrecks and the spark that created the A-Bomb, host Don Wildman unearths the true history of the Windy City.

Al Capone's rise to power coincided with the notorious "Roaring Twenties" period in Chicago. Capone and his fellow mobsters flooded the city with bootleg liquor, while buying off government officials.

John Dillinger, Machine Gun Kelly, Baby Face Nelson, and Bonnie and Clyde are some of the most notorious criminals of the last century. Technological advances like the Tommy Gun, V-8 engines with electric starters, and bulletproof vests often gave robbers the advantage over the police. A spree of robberies, killings and kidnappings during an 18-month period from 1933 to 1934 shook the nation to its core. The government responded with a war on crime that began with America's first national police force and the rise of the FBI. HD location photography, archival footage and evocative recreations are used to transport the viewer back to this era and to capture the hectic pace of this crime wave.
