7x6 - Star Trek: Hidden Frontier

Old enemies, old friends, and old ideas are shaken up as Siroc's plans shift ever closer to their devestating conclusion; things are collapsing right under the feet of the Allies as he draws nearer to his victory. Meanwhile, Shelby has to face up to the toughest challenge of her career with less help than she's ever had, Dao must face his past if he has any hope of going into the future, and the prisoners must make their stand if they hope to survive the seemingly mindless brutality of Siroc and his henchmen.
