Efenze, the President of the Board of Directors of government companies and a member of the Central Committee of the Ruling Party, eliminates his erstwhile business contractor, Sancheu, with the complicity of the latter's wife. His aim is to inherit Sancheu's widow and wealth and to forge his way into the Political Bureau of the Party. The Call of Blood is a dramatization of evil in its multifaceted dimensions including treachery, infidelity, greed, hypocrisy, double-crossing and vaulting ambition in a postcolonial society where those who wield political and financial power thrive or perish by their involvement in obscure schemes. The play is enriched by a great sense of dramatic economy and poetic style evident in the preponderant use of local imagery.
