She, along with other assassins, is sent to kill the protagonist Eddy Kay, who is unsure why people are trying to kill him. Along with the help of psychiatrist Dr. Anna Nolmar, he discovers that he was a test subject as part of a secret government program to create assassins that involved the use of sensory deprivation and brainwashing techniques. He was assumed to be dead, so when the government discover he is alive they try to have him killed to keep any knowledge of the program a secret.
Ms. Blue has two action scenes with the protagonists, the first is in a car park where she tries to stab Eddy to death. During a struggle the evil Ms. Blue manages to trip Eddy and pins him down under her leg; she tries to stab him but Eddy manages to break free and escape. Ms. Blue then resorts to shooting at him but Eddy escapes the car park inside Dr. Nolmar's car.
In the second scene Ms. Blue and another male assassin manage to track down Eddy and Dr. Nolmar to a hotel room they are staying in. They burst through the door when only Dr. Nolmar is there, Ms. Blue threatens Dr. Nolmar with a gun as she begs for mercy. The male assassin then throws Dr. Nolmar on to the bed and pins her down, he then takes his jacket off and starts punching her and the scene implies rape will follow. Ms. Blue takes great pleasure in watching this, as shown by the wicked grin on her face.
But before any rape can happen, Eddy bursts into the room and knocks Ms. Blue out by swinging a chain into her face. He then takes down the male assassin and forces a bloody Ms. Blue to make a phone call to her boss to inform him that she has killed Eddy. Ms. Blue is resistant to the request so Eddy shoots her in the leg and she eventually makes the call.
She is last seen in the hotel room with a bloody face and a bullet in her leg.
