Its 1929 Brooklyn New York, Ronnie and Roxy are assassin's part of an elite crime syndicate run by Al Capone.
Jack is a street wise cop after Capone, but Capone has set a price on his head.
Will Ronnie and Roxy kill Jack it's a deadly romance.
What will happen admits the murder, bootlegging and smuggling, in the Prohibition era.
(Just if you wanted to know In the United States, the term Prohibition refers to the period 1920 to 1933, during which the sale, manufacture, and transportation of alcohol for consumption were banned)
It was 1929 times were rough; the streets were constantly being bombarded, with rival gangs trying to sort out there issues.
To stay alive in this world you had to fight or kill.
Since the prohibition, every city was festering with crime from bootlegging to smuggling, everyone wanted to get their grubby paws on the good stuff; alcohol.
It was the era of Jazz drugs and drink, the only people who could control the mean streets, were street wise cops and even those guys where bad to the bone, some said even crazier than the gangsters themselves.
One of those mavericks was Agent Jack Branning; he used to be in the fuzz, but got kicked out for assaulting witnesses, he's nick name was "the heavy". He was the toughest cop Chicago had ever seen. But since being kicked out the force he had to go underground catch the criminals the police are to afraid to touch, he will bring them to justice by any means necessary.
Jack thought he had caught the biggest fish in the gangster pond he had Al Capone and his gang the Chicago Outfit right where he wanted them.
But Capone managed to worm his way out of it.
Capone and his gang fled to Brooklyn feeling the heat jack had started a round them.
But Jack won't give up that easily he wants Capone's head no matter what it takes even if it means going to Brooklyn.
As soon as Capone had arrived in Brooklyn talk had started.
"I herd that Capone is the world's deadliest, he orchestrated the Valentines Day Massacre" people whispered.
"I herd that he's on the FBI's most wanted list."
This chatter could be herd in the furthest parts of Brooklyn everyone cared about the city's newest arrival.
As the people of Brooklyn talked they had know idea what was arriving in their fair city, it wasn't Capone they had to worry about it was these two.
Arriving at Brooklyn's docks were the two newest members' of the elite Chicago Outfit.
They may look like your regular old broads, but looks can be deceiving.
These two where two of the best assassins the world had ever seen, femme fatale's dangerous they were.
Britain's worst people said, the deadly duo was their nickname.
But Britain's best I say because the deadly duos identity was never found out.
Teams and teams of cops investigated the case's trying to put a face to the crime, but they were no match for these two.
These girls were smart and deadly.
Ronnie and Roxy Mitchell there name was, and they were sisters.
The oldest was Ronnie her weapon of choice was the knife, people said that she had killed her own father in cold blood, cutting his throat with one swipe of her blade, people say she was so calm and poised that it was like she was cutting a piece of meat up.
Roxy the younger sister was more hands on, she was the charmer, the black widow, charming her victims then strangling them with a piece of cord. Roxy loved the hunt where as Ronnie loved the kill.
These girls were in Brooklyn as they wanted to become part of the family business, you see their aunty Peggy was married to Capone, and they were coming to America to help out with a certain problem.
All they knew was that there was a copper that needed to be exterminated.
What will happen when agent Jack meets Ronnie??
Does he know that she is after his life?
Will the sisters kill again so soon after arriving?
