The crew of the Garuda, including the surprise return of a younger Aron Kells, were busy working to save the population of the city of Bocasa. This city, the largest settlement of the Eth race on the planet Pleethion, was about to be engulfed by an unstable, volcanic mud dome.
One away team, under XO Commander Ross, was assigned to monitor the mud dome and investigate methods to stop its eruption. What no one could expect was that Commander Ross would turn rogue, kidnap Captain Reynolds, and abandon the rest of the team next to the dome. To compound his treachery, he had laid explosives aboard the USS Garuda to hinder their pursuit of him in a stolen shuttlecraft. Fortunately, Lieutenant Delano’s force shields prevented a lot of the damage to the ship.
Meanwhile, another team, led by 2O Lt. Cmdr. Calderan, was tasked with helping with the evacuation of Bocasa. However, they were surrounded and captured by Eth zealots who resented their presence on the planet. They were being taken to be sacrificed to the deity Sirilis, but they were rescued at the last minute as the Garuda restored its sabotaged transporter systems and beamed them back safely. The mud dome away team were likewise rescued, but not before LtCmdr. Alleran Tan got a limpet mine painfully embedded into his leg.
With the crew reassembled, the engineers and scientists on the Garuda worked to develop a plan to dehydrate the Mud Dome and save Bocasa, before beginning their pursuit of the wayward Harrison Ross and his captive, Capt. Quinn Reynolds.
