On the seventh night of Christmas, a passenger ship set sail for Mesalin. On board, twin siblings Sebastian and Viola perform a show for the guests. The wind and waves grew stronger, and the ship deviated from course with the wind and waves, crashing into a reef. The great waves shattered the ship and broke up the two brothers and sisters.
After the shipwreck, Viola was swept by the sea to Illyria. At that time, Illyria was at war with the merchants of Mesalin. In order to hide her identity, Viola cut off her long blonde hair, wrapped her corset, changed into a man's clothes, and disguised herself as a man to come to the Duke of Ossino and became a servant.
The Duke of Ossino never met his favorite partner. Recently, though, he had been courting the beautiful Countess, Miss Olivia.
Olivia's father died a year ago, and her brother left her not long ago. In memory of her brother, she vowed never to be with any man again. She declined all male visitors.
Her personal maid, Maria, conveyed her letter to the Duke of Ossino. Unless there are seven more cold summers, no man can get a glimpse of her in full. She would travel with a mask like a nun.
In order to gain Olivia's love, the Duke of Ossino sent Viola to see Olivia and express his sincere love to her.
Uncle Toby lives with his niece Olivia. Every morning, Olivia's maid from Maria always found the drunken Lord Toby in the garden.
Reckless and frank, Toby wants to save his niece from the grief of losing her brother. He chose Sir Andrew, who earned three thousand dollars a year in Illyria, and encouraged him to propose to Olivia.
As Maria describes it, Sir Andrew is definitely a stupid, grumpy and manipulative puppet. If it weren't for his cowardly character, I'm afraid he would have been killed long ago.
Whenever Andrew decides to abandon his marriage proposal and leave, Toby preaches about how good he is, and once Olivia sees him, she will be fascinated by him. Why was he in a hurry to leave? Here, he can enjoy delicious red wine and dance all night. Olivia would never marry someone of higher status than her. Andrew's persistence will surely win her heart.
Viola followed the instructions of the Duke of Ossino and came to Olivia's castle. No matter how much the butler Mavriot drove her away, it was useless. She swore she would stand in the doorway like a stake with a notice until she saw the beautiful Miss Olivia.
Her insistence intrigued Olivia, who suddenly wanted to see what the stinking lad in Marvolio's mouth looked like.
Viola's persistence won Olivia's pity, Viola's praise satisfied Olivia's proud vanity, and Viola's tenderness and affection fascinated Olivia. This heart-pounding feeling both excited and unnerving her. She did not want to accept the love of the Duke of Ossino, but she looked forward to seeing Viola dressed as a man again. She did not dare to show her love for Viola to everyone, but she was afraid of missing the opportunity to express her love to her.
She took off the ring in her hand and asked the housekeeper, Marvolio, to hand it to Viola, declaring that she would not take anything from the Duke of Ossino. Of course, the ring is actually her own.
The butler, Marvorio, threw the ring in front of Viola. With the woman's intuition, Viola realizes that Miss Olivia has fallen in love with herself as a daughter, but she has slowly developed feelings for her master, the Duke of Ossino.
Sebastian was rescued by Captain Antonio after the ship crash. The two men became friends. The death of his sister Viola left him in pain. In order not to bother Antonio again, Sebastian resigned and decided to go to the castle of the Duke of Osino to find an errand.
Olivia's butler, Marvolio, is a capricious, well-appointed, self-righteous middle-aged man. He lived a Puritan life with no interest in entertainment. He thought that the castle of the owner, Miss Olivia, was managed by him so that it would not be messed up by old Toby. After scolding Toby's gang despite his identity, Maria decides to join forces with Sir Toby, Andrew, and the castle musician Fis to teach Marvorio a lesson.
Maria mimicked Miss Olivia's notes, wrote a love letter, and threw it in the garden where Marvorio often walked. The self-righteous Marvario, when he saw the love letter, must have thought that Miss Olivia was in love with him. The letter will show him love in the name of the young lady and make demands on his actions.
This prank convinced Marvolio. In front of Miss Olivia, he put on knotted yellow socks, and in front of the servant, he held Miss Olivia and kissed her, calling her heart and liver baby, and even wanted to sleep with her.
Olivia was frightened. She thought there must be something wrong with Marvrio's spirit.
Sir Toby and Andrew took the opportunity to lock him up in a cell. In his dark cell, Marvorio desperately cries out for help, hoping to see Miss Olivia again to prove that he is not a madman. But even the priest who listened to his confession was disguised by the musician Feith, and who could he see?
The deeper Viola's love for the Duke of Ossino, the more troublesome her situation became. As a man, her master, the Duke of Ossino, could never fall in love with her, and as a woman, she could not give poor Olivia a future and happiness. But how could she watch her lover Ossino continue to suffer? She again asked to visit Miss Count Olivia.
After another reunion, Olivia could no longer hide her love for Viola, but her courage did not allow her to reap the love she had hoped for. Viola returned her promise ring and politely rejected her.
Olivia's love is so deep that she is willing to let go of her identity, regardless of reputation, and wait for the day when Viola grows up and becomes a "man".
After repeated refusals, The Duke of Ossino and Viola went to Miss Olivia's castle.
To ensure Sebastian's safety, Antonio also came to Illyria. He stayed with Sebastian and pulled out his wallet to let Sebastian buy what he wanted. But since he had been wanted by Ossino as a pirate, on the streets of Illyria he was again arrested by the attendants of the Duke of Ossino.
Fiss found Sebastian and took him to Miss Olivia's castle. Viola also came to Miss Olivia's castle as a man, once again showing her her master's heart. Two similar-looking figures, dressed in similar attendant costumes, appear in the same place.
Miss Olivia mistakenly recognized Sebastian as Viola and married him in the presence of a priest.
Sir Toby and Andrew mistake Sebastian for Viola and duel him, only to be beaten by him.
Antonio also mistakenly identifies Viola as Sebastian, and as a result, he exposes his identity by protecting Viola.
Everyone couldn't figure out what was going on until Sebastian and Viola stood together.
The two siblings eventually recognized each other. Antonio was released. Sebastian and Olivia fell in love, and the Duke of Ossino was attracted to Viola and married her. Sir Toby plucked up the courage to let the priest witness his love affair with Maria.
Marvolio was released. When he learned the truth, he was ashamed and eventually left Miss Olivia's castle.
