Write a short summary of what happens in the film

Globally, ocean garbage is a serious problem. 88%~95% of the ocean garbage is coming from the 10 rivers of Asia and Africa. The Mekong River is a transboundary river originating from China, passing through Myanmar, Laos, Thailand, and Cambodia and finally through Vietnam to the sea. Vietnam is the last stand of floating garbage from six countries before it goes to sea. However, The Vietnamese dumped garbage into the Mekong River and believed that the river becomes clean soon because it flows fast into the sea. The film is about a special boat struggling to collect floating waste from the Mekong River in Vietnam just before it enters the sea.

Cultural/Context information for the jury

- We visited the Mekong River several times to carry out the campaign, and we could often see people throwing garbage that they had collected from floating houses and ships into the river. We talked to various people in the area about the garbage problem, with a large number of local residents thinking nothing of dumping garbage into the Mekong River. The reason was that, to surprise, the river was believed to be clean soon because the garbage dumped in the Mekong River flows into the sea. - A large number of environmental campaigns undertaken to protect the Earth often inadvertently pollute the Earth in another way. However, our solar boat does not use a single gram of fossil fuel, Instead, only solar energy operates the boat and runs the conveyor belt to collect floating garbage. As a result, it emits nothing harm to the earth.
