In a global world increasingly estranged from nature, there are still people who tell stories about trees, fantastic beings with powers that go beyond our imagination. And for each of them, from the very moment their seed germinates, an elf becomes their inseparable companion; together they will grow, blossom, suffer. Their destinies are united forever. They are born and die at the same time, or at least that is what the old legends tell; but what happens to the city trees? They are now in danger. The trees are dying and with them their elves. There is only one way to help them... Save the tree!
