Herm is a microbe who's always looking for a new challenge. He has found a human being where he can do his thing undisturbedly: he infects each blood cell he comes across in order to multiply. In no time he's not alone anymore, with three or four new friends! In the body the microbes will come across all kinds of obstacles and pitfalls.
