Aegeon of Syracuse has come to Ephesus to seek his son, who went in search of his missing twin and mother months ago. Too bad that Ephesus has just declared war on Syracuse, and will instantly put to death any Syracusean found within their borders unless a ransome's paid. Meanwhile, the son, Antipholus, and his servant, Dromio (also an identical twin), keep running into strangers who seem to know them.
