Here's a simple plot to The Metamorphosis by Franz Kafka
Gregor Samsa wakes up one morning to find himself transformed into a "monstrous vermin". He initially considers the transformation to be temporary and slowly ponders the consequences of this metamorphosis. Unable to get up and leave the bed, Gregor reflects on his job as a traveling salesman and cloth merchant, which he characterizes as an exhausting and never-ending traffic. He sees his employer as a despot and would quickly quit his job were he not his family's sole breadwinner and working off his bankrupt father's debts. While trying to move, Gregor finds that his office manager, the chief clerk, has shown up to check on him, indignant about Gregor's unexcused absence. Gregor attempts to communicate with both the manager and his family, but all they can hear from behind the door is incomprehensible vocalizations. Gregor laboriously drags himself across the floor and opens the door. The manager, upon seeing the transformed Gregor, flees the apartment. Gregor's family is horrified, and his father drives him back into his room under the threat of violence.

With Gregor's unexpected incapacitation, the family is deprived of their financial stability. Although Gregor's sister Grete now shies away from the sight of him, she takes to supplying him with food, which they find he can only eat rotten. Gregor begins to accept his new identity and begins crawling on the floor, walls and ceiling. Discovering Gregor's new pastime, Grete decides to remove some of the furniture to give Gregor more space. She and her mother begin taking furniture away, but Gregor finds their actions deeply distressing. He desperately tries to save a particularly-loved portrait on the wall of a woman clad in fur. His mother loses consciousness at the sight of Gregor clinging to the image to protect it. As Grete rushes to assist her mother, Gregor follows her and is hurt by a medicine bottle falling on his face. His father returns home from work and angrily tosses apples at Gregor. One of them is lodged into a sensitive spot in his back and severely wounds him.

Gregor suffers from his injuries for several weeks and takes very little food. He is increasingly neglected by his family and his room becomes used for storage. To secure their livelihood, the family takes three tenants into their apartment. The cleaning lady alleviates Gregor's isolation by leaving his door open for him on the evenings that the tenants eat out. One day, his door is left open despite the presence of the tenants. Gregor, attracted by Grete's violin-playing in the living room, crawls out of his room and is spotted by the unsuspecting tenants, who complain about the apartment's unhygienic conditions and cancel their tenancy. Grete, who has by now become tired of taking care of Gregor and is realizing the burden his existence puts on each one in the family, tells her parents they must get rid of "it", or they will all be ruined. Gregor, understanding that he is no longer wanted, dies of starvation before the next sunrise. The relieved and optimistic family take a tram ride out to the countryside, and decide to move to a smaller apartment to further save money. During this short trip, Mr. and Mrs. Samsa realize that, in spite of going through hardships which have brought an amount of paleness to her face, Grete appears to have grown up into a pretty and well-figured lady, which leads her parents to think about finding her a husband.
