Five friends live by the bank of Ciliwung river. With all their differences, they are always together, calling themselves Ciliwung Troop. In the eyes of Wak Haji, they are always troublemaking brats. In the eyes of Adam and his friends, they are rivals to beat in every game, from rounders, swimming, to getek (a kind of raft) competition.
Problems spring up when a tomboy girl, Sissy appears. She is a granddaughter of the owner of tofu factory in their kampong, Babah Alun. The five’s friendship start to crack up while Ciliwung getek competition is coming up.
