Stuck in a deserted cavern, cut off from Kord, Pronto and the rest of their arsenal by a rockslide, Eli and Trixie find themselves outmatched and unable to hold off villains Locke and Lode and their deadly gattler blaster and ghouls. With only a few slugs at hand, Eli and Trixie will have to outwit and outrun the twins in a race to meet the other Shane Gang members and the rest of their slugs at the cavern entrance on the other side.
