The Idol tells a fictionalized version of the life of Mohammed Assaf, wedding singer from a refugee camp in Gaza who went to win 2013's Arab Idol singing competition. The film starts out in 2005 in Gaza. Mohammed is a young child, playing in a band together with his tomboy sister Nour and two friends. Recognizing the possibilities Mohammed's incredible voice has to offer, they set out to become a real band and are soon asked to play at weddings. Nour, however, collapses during a performance and is found to have kidney failure, requiring her to undergo weekly dialysis or for her family to buy her a kidney transplant. As the transplant is far too expensive, Mohammed makes it his goal to raise enough money as a singer to purchase it. He takes singing lessons and befriends a girl named Amal, also suffering from kidney disease, during Nour's dialysis sessions. In spite of treatment, Nour dies, and Mohammed is left disillusioned and depressed. Seven years later, in 2012, Mohammed performs with a band for the showPalestinian Idol, but the travel restrictions on Gaza prevent him from actually going to the studio in Ramallah and force him to perform over Skype. The poor conditions of Gaza electricity affect the performance, frustrating Mohammed, who wants to quit singing until he meets Amal again. She inspires him, and with the support of his family, Mohammed decides to audition for Arab Idol. Crossing the border from Gaza into Egypt, where the auditions will take place, is near impossible, and Mohammed gets caught with a fake passport at the Rafah Border Crossing, but after performing a religious song for the border clerk, he is admitted through, with a warning that it may be difficult for him to ever return. In Cairo, Mohammed finds the auditions already underway and all the slots taken, forcing him to break into the building where a young singer offers Mohammed his slot after hearing him sing on the toilet. Mohammed successfully auditions for the show and is soon is allowed a pass to Beirut to take part in the main competition. As the show progresses, Mohammed's reputation grows among the Palestinians, who are shown to be ecstatic that a Palestinian man is performing so well and winning such acclaim, emboldening the Palestinian national pride and inspiring hope and optimism. The pressure of this gets to Mohammed, who has a panic attack right before an important rehearsal. With the support of one of the audition judges and Amal, Mohammed picks himself up and gets back to performing. The film ends by switching to real-life footage of Mohammed Assaf winning the Arab Idol title, followed by a brief overview of Assaf's life after the finale.
