Deachtóir cruálach is ea é. Cuirtear i leith Tintin agus a chairde go raibh baint acu leis an éirí amach agus tá siad anois i mbaol báis. An mbeidh Tintin in ann deireadh a chur leis an réimeas míleata agus síocháin a athbhunú sa tír? Cén ról a bheidh ag an gCarnabhal bliantúil ann — agus ag cleamairí ó Ard Mhacha?

The Picaros, revolutionaries, have revolted against General Tapioca in San Theodoros. He is a cruel dictator. Tintin and his friends are accused of being involved in the uprising and are now in danger of death. Will Tintin be able to end the military regime and restore peace in the country? What will be the role of the annual Carnival – and of Armagh clerics?
