A small beach resort is rattled by the suspicion that there are sharks in its waters. 14-year-old Rosina thinks she saw something in the water, but no one seems to be paying much attention to her.

When her father recruits her to do house maintenance work, she meets Joselo, a slightly older fisherman.

Among dirty swimming pools, pompous gardens and deserted beaches, Rosina experiences something new: a desire to bridge the distance between her body and Joselo’s. But the feeling is hardly mutual. To get his attention, she comes up with a convoluted, poorly planned strategy, going about it stealthily and menacingly, as if inspired by the mysterious predators.
