The crazy and penniless chemist Khosro discovers a new, powerful washing powder for which he hopes to receive the Nobel Prize and become a rich man. In an attempt to sell his formula to Jam, the president of a local washing powder factory, Khosro had a fatal accident. Jam on the other hand faces bankruptcy and workers strikes. In his impotence, Jam suffers a heart attack and is taken to the same hospital as Khosro was. The hospital's neurosurgeon has a far-reaching idea about how to make use of Khosro's alive brain and Jam's alive body, which results in a hilarious and entertaining mess.
