Egeon’s remaining son, Antipholus of Syracuse, and his servant, Dromio of Syracuse, come to Ephesus, where—unknown to them—their lost twins now live. The visitors are confused, angered, or intrigued when local residents seem to know them.
Similarly, Antipholus and Dromio of Ephesus run into puzzling reactions from the people they know—who have been dealing, unwittingly, with the Syracusans. Antipholus of Ephesus’s wife bars him from his house; he is jailed after a jeweler claims he owes money on a gold chain he never received.
When the four twins come together, all is finally resolved. In one last twist, their parents reunite as well.
