18 years on from the devastating impact of 2004's tsunami, the world still fights to come to terms with this devastating environmental disaster. Little does humanity know that it is about to face the ultimate peril; a monumental death wave annihilating everything in its wake. With the threat of another catastrophic tsunami, Prime Minister Tribhop sets up a national disaster alarm centre. His political future and the lives of his people depend upon the decisions he makes. But no one predicts the enormity of what is about to rise from the Thai Gulf. And no one can out run it this time. The Death Wave is coming 差到一逼。 2022年，泰國總理戴蓬髮布災難預警法，設立亞洲太平洋預警中心，由總理的心腹沙炎博士出任院長。此外，預警中心有3名熱愛大自然年輕工作人員，雖然平時工作中互相競爭，但私底下相親相愛猶如一家人。沙炎博士預測到未來將發生大地震，於是總理戴蓬髮布緊急疏散令，但博士計算錯誤，大地震並沒有發生，導致民眾對總理不滿，政敵也乘機施壓。沙炎感到愧對完全信任他的總理。 不久，沙炎博士再次觀測到大地震信號，但是無法準確預測時間。博士認識到他的責任重大，馬上報告總理，但總理擔心又是誤報，此次是否要緊急疏散民眾呢？ 最後大災難終於發生，地震引發大海嘯，超過200米的大海浪沖入曼谷，摧毀捷運，全市落雪。總理和博士他們要如何應對這次災難呢？
