Akeem (Eddie Murphy) is the prince of Zamunda. He and his attendant Sammi (Arsenio Hall) come to the United States for a 40-day visit in disguise. For Akeem, there was another purpose for this trip. He was very dissatisfied with the marriage arranged for him by his father, Gavi (James Earl Jones), so Akeem decided to find his right girl in America. Fortunately, such a woman soon appeared. Her name was Sally (Shari Headley). In order to get close to Sally, Akeem entered the bakery owned by Sally's father and became a migrant worker. Sally has a boyfriend with a very rough personality. In contrast, she prefers the gentle and gentle Akeem. Just as the relationship between the two was gradually getting on the right track, Kafei actually came to the United States. Akeem's identity that he had carefully concealed was about to be exposed.
