A terrible misunderstanding between a mouse and a frog provokes an escalation of reprisals and revenge that will culminate in the war between the people of Mice and the people of Frogs who both live on the edge of a field. But a real threat to this small world at war comes from somewhere else. Inspired by Batrachomyomachia (Battle of Frogs and Mice) a comic epic attributed to Homer.
