Ulysses (disguised as a beggar) tells his most trustworthy man before he left before war, Eumaeus, and is talking about Ulysses and that Ulysses knew him before tragedy came. His son, Telemachus, walks in and Ulysses cannot bare his words and shows himself.
Ulysses, under disguise, goes to Penelope, his wife, and tells her of stories that he had with himself, and the stories of his adventures to different islands. He then told her to pick the suitor that would be Penelope's new husband if they could shoot Ulysses old bow that was secretly and almost impossible to shoot the bow. He knew no one would be able to shoot arrows but him.
After all the suitors unsuccessfully attempted to shoot the bow, it was Ulysses turn and he bent the string back with ease, putting the arrow on, and shooting it through the rings and got a bulls-eye. He then fought all the suitors, killed them, and got his wife back.
