簡介：非洲中南部讚比亞的草原上生活著許許多多的河馬。它們是陸地上體型最大的哺乳動物之一，它們的大嘴每天就要吃掉大約40公斤的草。雖然雨水充沛的季節，瀉湖與河流當中不乏食物，但幹熱季節到來的時候，它們就將食不果腹。饑渴襲來的時候，一種可怕的瘟疫竟也隨著到來。瘟疫像魔鬼一樣橫掃盧安瓜河谷，許多河馬開始死去。為什麼瘟疫隨乾旱到來，它對於河馬是一種怎樣的災難？隨著幹熱季一起到來的炭疽熱在河馬們安家的盧安瓜河谷中肆虐，使得原本由於缺水和饑餓已經非常脆弱的生命更加難以承受。空氣中，水源裏到處都是炭疽熱病菌，受到感染的河馬一頭又一頭死去。河馬找不到一個安全的地方躲避災難，也沒有辦法對突然出現的疫病進行防禦。不知道這場奪去許許多多河馬生命的災難要到何時才能夠悄然退去？收起
