Despite his normal demeanour, Iris soon senses danger when Richard parks his car too close to hers, effectively trapping her between the vehicles. Seizing the opportunity he injects her with a paralytic agent that will render her immobile and unable to speak within 20 minutes. She takes off running for her life, trying to escape the psychopathic serial killer who is relentlessly pursuing her. Will she be able to make it to safety before she becomes incapacitated? This film has moderate suspense and a decent premise, peppered with a few plot holes. Overall it’s is an adequate time passer.
