Twelfth Night is a romantic comedy filled with mistaken identities, love triangles, and witty humor. The play begins with a shipwreck off the coast of Illyria, where Viola is separated from her twin brother, Sebastian, whom she believes drowned. Disguising herself as a young man named Cesario, Viola enters the service of Duke Orsino.

Orsino is in love with Lady Olivia, who is mourning her brother’s death and refuses his advances. Orsino sends Cesario (Viola) to woo Olivia on his behalf, but Olivia instead falls in love with Cesario, not realizing he is actually Viola in disguise. Meanwhile, Viola secretly falls in love with Orsino, creating a tangled triangle of affection.

In a parallel subplot, Olivia’s steward, Malvolio, becomes the target of a cruel prank by her servants and relatives, who trick him into believing Olivia loves him. His strange behavior leads to his humiliation and imprisonment.

The confusion peaks when Sebastian arrives in Illyria, and everyone mistakes him for Cesario. The twins are joyfully reunited, and all is revealed. Olivia marries Sebastian, and Orsino realizes his love for Viola, who reveals her true identity. The play ends with multiple marriages and restored harmony.
