 Captain Ekumu has a lot on his mind: his son Ika is dying and he does not have the means to find treatment for him, which is driving his wife Ezéni to despair. A mysterious radio broadcast interrupts the speech of President Baby Zame. It talks of a golden mango tree, of a day to come, of the freedom of poets. Liberty holds sway on the airways it pirates for fifteen minute periods from its hiding place in a truck. Colonel Paturau is ordered to announce a bounty prize to anyone able to arrest pirate Liberty. But how can you arrest a voice that has no body? A culprit must be found. For Ekumu, this could be the solution to his family tragedy.
