Experiment in Terror (1962)

Under the cloak of night, bank clerk Kelly Sherwood returns home from an exhausting day at work, only to find herself ensnared in a web of fear woven by a shadowy stranger. This unseen antagonist, masked by the shroud of darkness and distinguished by his haunting asthmatic voice, knows every detail of Kelly's life and routine. A chilling ultimatum is placed before her - she must rob $100,000 from her place of employment or face the unthinkable consequence - the death of her sister Toby. The stranger's threats hang heavy in the air, an omnipresent terror that invades every inch of Kelly's existence. However, she refuses to succumb to the tormentor's scare tactics. Realizing that the predator is asthmatic, Kelly turns the tables and sets a trap to ensnare the criminal. In her struggle for survival and justice, she reaches out to the FBI, finding an unlikely ally in Agent John 'Rip' Ripley. Ripley, an astute and seasoned agent, provides Kelly with crucial advice and safeguards her and her sister with a team of dedicated agents. But as the nightmarish reality escalates into a terrifying crescendo, Toby is abducted, and Kelly finds herself in a race against time—caught in a deadly game of cat and mouse. Mustering all her courage and wit, she works with the FBI, determined to outwit the criminal and save her sister.
