The third feature film by the brothers Howard and Jon Ford is an unabashed throwback — fan service for horror buffs who long for the glory days of George Romero zombies. The dilapidated shamblers of The Dead dominate a post-apocalyptic African landscape ravaged first by war and again by a walking dead (of unspecified origin, natch) whose population is slowly overwhelming its still-living counterparts. Avoiding their bite is a full-time job for an American engineer (Ron Freeman) who was the sole survivor of a failed evacuation attempt that left him stranded on the barren West African countryside. Having liberated an old pickup truck, he connects with an African sergeant (Ghanaian actor Prince David Osei) who’s trudging toward a fortified military base where he believes his young son is living as a refugee from the dead. The two men forge an alliance and press northward together, conserving food, water and ammo as they head toward an uncertain salvation.
