Ocean Heaven is about a
terminally ill father, Sam Wong/Wang Xincheng (Jet Li) as he works his job in an aquarium and struggles to look after his 21-year-old son with
autism, Dafu/David (
Wen Zhang). Sam has single-handedly brought up his son since his wife died in a swimming accident 14 years ago and looks after him day and night. Upon discovering Sam has less than five months to live, he multiplies his efforts to help Dafu learn basic tasks in order to care for himself, as well as searching for a home for him, before he passes away. As the story progresses, the growing relationship between father and son, as well as the community around them, become clearer. Ling ling (
Gwei Lun-mei) plays the role of a clown who is part of a small traveling circus (they perform in the aquarium for a short period of time) and who gets on well with Dafu, leading to a close friendship between them. Though Dafu struggles to learn many basic tasks, Sam perseveres in teaching his son the tasks that he will need to know how to perform himself once his father dies. Though Sam never gave up teaching and explaining things to Dafu in a positive and supportive and memorable manner, he did contemplate ending his and Dafu's existence together rather than leave his child to suffer without him. Sam, at this point had yet to tell anyone how far his health had deteriorated, until one day while returning from their hometown, his neighbor tells Sam his doctor came from the city with bags of free medicine and waited two hours for him. Meanwhile, Principal Liu, of the boarding school for mentally challenged children that Dafu attended as a child, recommends Dafu to a newly opened institution where he can stay after his father dies. Dafu continues learning, though Sam must move into the institution with him to help him adjust. Ling Ling, knowing that she is about to have to leave with her circus, teaches Dafu to pick up the phone in the aquarium when he hears it, and she will talk to him. Ling Ling leaves with her circus. Sam, for the first time in the movie, swims in the aquarium with his son, dressed in a sea turtle costume he made by hand, telling his son not to be afraid when he is gone; he will be like the turtles in the aquarium, always swimming close by with him. He almost drowns but is helped from water by Mr. Tang and while they chat, Sam reveals his wife's death might not have been an accident as she was a very good swimmer and they had recently found out Dafu is autistic. Sam doesn't blame her for not being able to handle their son's circumstances. There was only one instance in which Sam loses his composure with Dafu, while he is nearing the end, and still working and trying to teach his son how to do his job, Dafu is distracted and Sam yells at him. Less than a moment later and Sam is already mending fences and reassuring his son. Sam eventually dies, and his funeral is attended by close friends and family. Dafu waves good bye to the sky/Sam, as it seems he has learned people live there, something Ling Ling explained to him earlier when she spoke of her grandmother with him before she left town. After the funeral, Dafu is seen doing some of the things that his father struggled so much to teach him with success. He cooks by himself, knows how to ride the bus, and picks up the phone when Ling Ling calls, and working at the ocean park, a place Mr. has opened the doors for Dafu at any time of the day. It is implied that from then on, Dafu will know how to lead his life on his own, though he still has Sam's old friends helping him along the way. ==Cast==
