A Story of four friends: Selim, a migrant worker who can't go home; a gay couple, Rahman and Franco; and Sungil, who is disabled.

Selim is a migrant worker in Korea who is preparing to return home. He needs a place to stay for a while—he visits a furniture factory town to meet his friend Rahman. Rahman introduces Selim to his special friend Franco. Selim's heart aches when he hears from his family, who ask Selim if he can stay in South Korea and continue to send money to the family. From then on, Selim spends his everyday life with Rahman and the others. He finds his true family, friends, and himself. Since Selim can't go back to his home country at the request of his family, he gets a job at a furniture factory. When Franco, who was not a registered migrant, is forced to leave Korea, Rahman falls into sadness. While being chased by immigration crackdown officers, Selim gets severely injured…

As of 2023, there are 2.43 million migrants in South Korea—1.3 million of whom are migrant workers and 430,000 unregistered migrants without visas. Migrant workers are working in precarious and dangerous industries where Koreans do not want to work and are treated as machines because of their skin colors and language barriers. Sometimes, their families back home treat them as money machines. Eventually, they become isolated and fail to be a part of either community.
Director SHEKH Al Mamun was born in Bangladesh and lived the life of a migrant worker at a furniture factory in Maseok, Korea, in 1998. He said in Unplug, "Migrants are everywhere; they are always with us, and it is an unstable and difficult journey to leave the birthplace and live in another country."
