When an ambush by invading aliens destroys the planet's primary and secondary lines of defense, the military misfits of Polliwog Base must step to the plate to defend the planet. With no idea who the invaders are or why they've come, the Polliwogs have little time to find their answers and help Command mount a defense. The day we've long feared has finally arrived... and we're not ready.
