The tans invade green territory. Sarge is a top dog in the green army and is sent off to war. Green intelligence learns of three keys that the tans are looking for. They don't know their purpose or where they are but they do know that they need to get them before the tans do. After meeting a retired tan general, Sarge learns that the keys open a portal, to what, he did not say. As the result of many battles and dozens of green soldiers deaths, Sarge finds all of the keys and puts them in place to open the portal. It opens and he walks in and finds himself on a giant countertop.

Somehow Sarge makes it back to the plastic world and tells his leaders of where he'd been. But it's already to late. General Plastro (the evil tan commander) has already taken over this strange land. And he is useing it against the green army. Suddenly reports of huge magnifying glasses melting down entire platoons of green soldiers began to flood in. The greens must take action. They must clense the land of the tan infestation at all costs.

Now Sarge and his squad of five elite soldiers known as the Bravo Company Commandos are ready to kick ASS and take names. But the odds are against them. Plastro has control of giant insects the size of a man, he is using giant stoves to melt men down, he has a strange machine called the V-Bot that can destroy anything, he even has control of a giant fierce beast known as Precious the Poodle. Sarge well have to use all of his skills to win this one.
