When the humans of the home aren't looking or paying attention, the toys fight eachother in an endless war across a young boy's bedroom all the way to the living room including the back garden.
These toys who fight each other are three inch garrison of Napoleonic War British Army era soldiers, scifi space marines, samurai warriors, cowboys, native Americans, First World War era German troops, mutants, orcs, medieval knights, Vietnam War US marines, American Civil war Union and Confederate soldiers too who are locked in a seemingly endless fight when the humans are not noticing.
Meanwhile, Private Bradbury and his fellow toy redcoats were held up at a fort made of building blocks in the bedroom taken from the samurai as they try to fend off a vast horde of mutants who were attacking the fort.
