A wagon train is headed through the western plains on their way to California and they are attacked by a tribe of Red Ants. The wagon train is surrounded and the calvary tries to come to the rescue and they are chases off by the Red Ants. The cavalry calls on Atom Ant to come to the rescue.
Atom Ant flies out and sees the situation and meets with the chief of the Red Ants, Big Deal. Big Deal tells Atom Ant if he can beat his son in a fight, the Red Ants will let the pioneers go on their way but if his son wins, everyone is his prisoner. Atom Ant agrees. The son is a huge Red Ant and he knocks Atom Ant into a papoose at first. They are then tied at the wrist and Atom Ant starts flinging around his opponent. Then in the last battle, they must use tomahawks. The son gets a huge tomahawk and throws it at Atom Ant. Atom Ant gets the tomahawk and rides it back at the son and the son gives up.
Atom Ant makes a deal with Big Deal and he and his Red Ant go with the wagon train to get parts in westerns in Hollywood.
