Paranoia Fuel: A central theme of the show is that the flaws in new technologies are being exploited to commit crimes. Imagine getting a heart transplant, only to find out later that someone has implanted a timer in it that will stop running if you don't pay a ransom.

Complete Monster: Giulio Sacchi is a two-bit thug looking to hit the big time. After a failed job, Sacchi rapes his girlfriend to blow off steam before deciding to kidnap a young woman who happens to be the daughter of a very wealthy man. Giulio and his gang purchase guns from a supplier who requests a hefty security deposit so the guns will not be used for murder, but Giulio promptly murders the old man and his wife before kidnapping the target and killing her boyfriend. When she flees to a nearby house, Giulio kills the old man at the house to make a point to the rest of the family and accidentally shoots the little girl when she surprises him. Without remorse, he massacres the rest of the family and proceeds to murder his girlfriend to keep his cover while confessing to her he has no remorse. After abusing his captive, he kills her after he gets the ransom and kills his friends as not to share it.
