In the bright summer days, a group of teenagers swim lengths in the swimming pool. Their spirit is united for the upcoming swimming gala. Before they formed this team, someone had left the group and someone had even thought about giving up swimming.
The ‘Angels’ faced many difficulties before becoming a proper team. The team founder, TAK, has two daughters. His elder daughter, HAN (CHAN MAN WOON, BO BO), frequently argues with her younger sister, WING (TONG LEILA), who has been separated from the family for many years. They are both in love with the team captain, LOK (SIU EDWIN). WING used to live with her mother. When she finds her father, she is disappointed with the new family. She fights with HAN constantly and joins the opposing team, the ‘Devils’, to annoy her.
