The Thunder Boys are K-pop heartthrobs whose talent agency has left them in hot water: The company is in financial trouble and has been struggling to pay its staff. The five-member group comprises leader Choi Ho-rang, dance supremo Shin Tae-ho, rapper Jo Yi-joon, lead singer Eun Young-min, and the super-popular Yoon Sang-woo. The boys are thrown a curveball when their agency’s financial troubles lead to them taking charge of a struggling supermarket – and tasked with turning its fortunes around. The boys have never known anything but K-pop, but all of a sudden need to learn how to stock-take, stack shelves, work tills, chop meat, and gut fish! Can they turn the supermarket into a local success story – and re-start their musical careers while they’re at it?
