When a distress call comes in, the Enterprise must aid a large colony ship of alien refugees known as the Perenorean, who are under siege by an unknown enemy. But Kirk and his crew will find that the situation with the peaceful Perenorean is far more complicated than they bargained for, and the answers as to why they were attacked in the first place unfold in the most insidious of ways....
