From the first scene, it's clear that our hero, Shafa, is no ordinary girl. She races motorcycles, defends weaker friends, and saves animals from danger. Shafa lives with her father and two siblings on the island of Singo, a fishing community with strict rules. It is ruled by a local rich man who thinks money can buy everyone and everything. One day, Shafi's dad catches some very rare crabs, called horseshoe crabs, whose blood is worth a lot of money. The profit from their sale is to be distributed among all the island's inhabitants. But Shafa feels bad for the animals and releases them into the sea at night. Anger and blame fall on her father and the whole family faces the unpleasant consequences. The brave girl, however, refuses to be cast out by the locals. She sets out for a nearby island where rare crabs are said to live to save her loved ones from impending disaster.
