Located on the Southeast of the Korean peninsula is the international city of Busan. A popular vacation spot on the East Sea coast, Haeundae draws one milion visitors to its beaches every year.
Man-sik, a native of Haeundae, went deep-sea fishing four years before and lost a co-worker in a tsunami; he has never returned. He now leads a simple life running a small sushi shop and is preparing to propose to his longtime girlfriend, Yeon-hee.
While these seemingly banal domestic affairs unfold, geologist, an expert on tsunami research, discovers the East Sea is showing signs of activity similar to the Indian Ocean at the time of the 2004 tsunami.
Despite his warnings, the Disaster Prevention Agency affirms that Korea is in no harm of being hit. When he discovers a super tsunami starting in Tsushima, Japan is headed straight for the Korean peninsula, he quickly heads down to Haeundae. Eventually, Kim gets a call about a deadly oncoming wave, with only ten minutes to spare. While the vacationers and citizens of Busan are enjoying a peaceful, hot summer day, a super-tsunami is headed straight for Haeundae.
