Tamara and Tatiana are twins. They love visiting their Aunty Rita.

Aunty Rita lives in a small house by the forest. She loves living here and making plant syrups keep her happy. The twins have to try the syrup every time they visit. Sometimes they visit together, sometimes they visit alone. But one day things are strange when Tatiana visits, and the children begin to see that something isn't right. When Tamara visits, things aren't just strange, they are dangerous. The twin's parents don't know what to do, but Tamara has an idea. An idea that could help the whole family.
