In the midst of the African savannah, in the safety of their six-meter-high tower, over a million termites are hard at work when disaster suddenly strikes: a deluge of tropical rain floods galleries and chambers provoking panic and chaos. The cracks and breaches in the termites' castle are an open invitation to a horde of terrible, carnivorous ants to invade, threatening the colony's survival... Starring real insects, The Besieged Fortress is a suspenseful wildlife fiction shot like a true disaster movie, using pioneering techniques to provide exclusive footage and give us an unprecedented insight into a fascinating world.
