Cymbeline, the King of Britain, is angry that his daughter Imogen has chosen a poor (but worthy) man for her husband. So he banishes Posthumus, who goes to fight for Rome. Imogen (dressed as a boy) goes in search of her husband, who meanwhile has boasted to his pal Iachimo that Imogen would never betray him. And Iachimo's determined to prove him wrong.
Second Gentleman
Iago and a comrade-in-arms are outside the Venice home of Desdemona's father, who does not yet know that she has eloped with Othello. Iago confides to his friend -- who had hoped to marry Desdemona -- that he serves Othello to further his own ends. Venice needs Othello to protect its commercial interests in Cyprus where the Turkish fleet is headed. Desdemona insists on going to Cyprus, too. In Cyprus, Iago plots to convince Othello that Desdemona has betrayed him with Cassio. A lot more than political ambition seems to be motivating Iago.
