A series of burglaries, followed by Nicholas's bike being stolen, prompt Robert and Jerri to buy an alarm system. Robert doesn't want to pay for the high cost of installation so he hires Derek and Wendell to do the job. Derek and Wendell are complete amateurs and fail to install the system properly. That evening the alarm goes off several times waking the family and bringing police to the door. When the alarm is finally disabled, Robert and Jerri talk about what happened and decide they can feel safe without a security device.
