Four adopted brothers – Jojo (Awie), Fairil (Afdlin Shauki), C’tan (AC Mizal) and Khai (Hans Isaac) – leave their kampung and head to Kuala Lumpur to make it big in the cleaning business. Fairil, the most ambitious of the four, inspires them to enter the Window Washing Olympics for the most coveted contract of all – cleaning the windows of KLCC. But the brothers would have to survive the allure of organiser CJ (Erra Fazira) as well as stiff competition from current champion and contract holder Wira (Khir Rahman) to win the title.
