While the boyfriend becomes completely absorbed in catching fish, the stranger gradually wins the girlfriend's attention with promises of easy money and constant encouragement. As the hours pass, the distance between the couple grows, hidden conversations multiply, and innocent fishing lessons become a web of distractions, misunderstandings, and carefully timed interruptions. By the time the boyfriend begins to suspect that something else has been happening on the riverbank, the truth is already impossible to ignore.
