Decalogue 10 "Thou shalt not covet thy neighbor's wife, nor his manservant, nor his maid, nor his goods, nor anything that is your neighbor's." A man dies leaving an extremely valuable stamp collection to his two sons, Jerzy and Artur. Although they know very little about stamps, they are unwilling to sell. They learn that one very rare stamp is needed to complete the valuable set. To acquire the stamp Jerzy donates his kidney - the man in possession of the stamp is in need of a kidney for his daughter. Returning from hospital, Jerzy and Artur find that they have been burgled. The entire stamp collection is gone. Shamefully, they confess that they suspected each other and are reconciled.
