An omnibus comedy set in a newly built housing complex, the film follows seven interconnected stories about the everyday vices simmering behind thin apartment walls. The film observes the lives of ambitious young couples, suspicious spouses, self-styled rationalists, overworked husbands, and gossiping neighbors navigating the promises of modern apartment living.
