The play takes place in Venice. The Moorish General, Othello, secretly marries a nobleman's daughter, Desdemona.
Arise black vengeance from the hollow hell!
Othello and Desdemona are attempting to build a life together. However, their relationship is sabotaged by the evil ancient, Iago. He orchestrates numerous plot threads around symbolic items such as Othello's handkerchief to convince him of Desdemona's adultery.
Othello is sent to defend the Island of Cyprus from Turkish Invaders. Iago tells the audience his plan to split up Desdemona and Othello. Part of the plan includes getting Cassio, a lieutenant, fired from his position.
Iago plants a handkerchief of Desdemona’s in Cassio’s room to make it appear that the two have been together. Othello finally believes Iago, and vows that he will not stop until he has his revenge. Othello's fate is reversed, as he is heading towards his eventual doom (Perepetia).
Iago's intricate web of lies has been set, and now the plot threads are beginning to unfold in the climax, as Othello kills Desdemona and Emilia walks in.
Othello kills himself and Iago is taken away to be tortured. The audience is left with disbelief and despair, but some satisfaction that Iago is found out.
