Rookie troopers Rico, Flores and Jenkins journey to Pluto as part of Alpha Team "Razak's Roughnecks" on what is supposed to be a simple mop-up operation, but find a major threat to the research stations from plasma-shooting alien Bugs.

As the war moves to the planet Tophet, the Roughnecks go after Razak and Higgins, who are trapped behind enemy lines and about to be blown up by their own air strike.

Higgins summarizes the current state of the war on Pluto and Tophet in clips from previous episodes.
