On Haeundae Beach, a guilt-ridden fisherman takes care of a woman whose father accidentally got killed. A scientist reunites with his ex-wife and a daughter who doesn't even remember his face. And a poor rescue worker falls in love with a rich city girl. When they all find out a gigantic tsunami will hit the beach, they realize they only have 10 minutes to escape.
