The comedy, which raises questions about art and friendship, concerns three long-time friends, Serge, Marc, and Yvan. Serge, indulging his penchant for modern art, buys a large, expensive, completely white painting. Marc is horrified, and their relationship suffers considerable strain as a result of their differing opinions about what constitutes "art". Yvan, caught in the middle of the conflict, tries to please and mollify both of them (taken from Wikipedia).
