It all begins in a beautiful village in Chiapas Maya, we see indigenous walking ALBERTO (25) JANA (22) winks her eye, she is the enemy of YAACUNA (19). In the mist of healing smoke is CHIICH, the shaman, the medicine old woman.
In a bath the sensual brown skin of YAACUNA is covered by flowers, (this bath is a cure to heal the soul). When her grandmother is waiting with a towel she has all the knowledge of the ancient Mayan healing. Yaacuna is only thing of the afair with Alberto, and going to the town’s dance.
That afternoon a child arrives is BENITO. Grandma CHIICH treats him lovingly and gives him some money to buy food. Two mysterious rich men come and ask her for healing herbs, Chiich realizes their evil intentions. They work for Large lab companies are trying steal the medicines.
Later on Grandma CHIICH and YAACUNA take a walk by the river grandma tells her¨. This healing knowledge should continue, as it is not mine, nor yours but of our people, its must be passed as this leaf in the river, without stopping…
Yaacuna realizes that CHIICH has weakened, she is sick. The next morning they realize that the harvest had been attacked by a plague, not have to eat; to make it worse Alberto is leaving to study college in the city. Yaacuna because of puberty and love goes follows after him, without knowing that her opponent JANA will take her place as assistant to Grandma Chiich.
Yaacuna is trying to sell herbs at the market initially has difficulty due to internal market mafias and threats sent by the pharmacy across the street. The idyll ends with Alberto, for he is a young city life, you do not understand, this wound. When they Chich and Yaacuna talk over the phone, Yaacuna begins to notice that something is wrong, Jana surprisingly compassionate. The Two MEN approach to JANA and give money to her, without a logical reason.
Yaacuna is warned by BENTITO (a child of the people), that her grandmother is seriously ill may not last very long. She leave city. Upon arriving she realizes that Grandma is in bed, she realizes that Chiich´s cup has remains of herbal tea that is poisonous in high doses. Yaacuna and confronts Jana, she admits that poisoned her due to envy, and that she was paid to do it, by people from a big pharmaseutic company as she did not give away the recipe for some medicines.
Large lab companies are trying steal the medicines. The old healer is sick and wants to inherit the power of healing through the Mayan legacy to the girl she adopted few years ago Yaacuna, but she is only interested in leaving her home town and experience the modern world.
Yaacuna rushes into the depths of the jungle, in order find herbs that could counterpoise the effect, the jungle dangerous, an snake bites her, when he gets home from Chiich with the remedy, she is too weak to ingest but asked to continue with the healing and says that magic is not in the grass but in the silent love of the healer.
JANA remains free. Chiich buried in the river near where she used liked to walk. Yacuuna places a leave on the river and understands that herbs are only the means to heal the soul, and becomes the town healer.
