Detectives Cerreta and Logan investigate the death of a young man, Roberto Martinez, who died of a heart attack behind the wheel of his car. Despite his young age, Martinez had a pacemaker which apparently failed. His family is suing the company that manufactured the pacemaker but they also want a criminal investigation. What they learn is the the device implanted in Martinez was previously used in another patient. The doctor in that case claims she donated the device to a medical school after her own patient received a new one. The pacemaker was acquired and refurbished by Bruce Sutter but it appears he may have changed the expiration date of the battery. A detailed examination however reveal's the problem may have been one of quality which leads them back to the manufacturer and eventually charge the owner's son, Steven Cleary, with murder.
