"Marooned" Part 3: Trapped on an alien world and surrounded by bugs, Tanner's Tigers are left with one option — the help of a man known only as "The Captain." Meanwhile, an experimental Exo-Suit is sent down to find them, with a trooper who's name is very familiar. Can the Tigers get the research vessel working and get off the planet before SICON nukes it to dust? And if so, who will sacrifice themselves to enable it?
