Introduction
The Enterprise receives a distress call from the USS Lantree, a nearby supply vessel. Upon arriving at the ship, they find that its entire crew, including its 30-something captain, dead of old age. Following the Lantree's path back to its last stop, a genetic research facility, they find the scientists there suffering from the same mysterious condition. Dr. Pulaski is torn between her duty to protect the Enterprise from harm and her duty to help people in need. How far will Dr. Pulaski go to satisfy both? And does the scientist's research hold the answer to this dangerous puzzle?
