This is the story of a vegetable garden, from the first seeds to the harvest. But this garden is different, because here the gardener has decided to banish pesticides and other chemicals, and to be helped only by discreet workers, the insects. As we dive into the heart of this plant kingdom, we discover thousands of tiny lives that organize themselves as in a micro-society: decomposing insects, recyclers, pollinators, the workers of the garden work to maintain a fragile balance within the vegetable garden. As the plants grow and begin to produce their first vegetables, the incredible interactions between insects and plants help protect the future harvest. But it is also their personal stories that punctuate the life of the garden. Between parades, mutual aid and attempted putsch, the story of the vegetable garden thus takes the form of a true nature tale.

Three teenagers — Amelio, Blake and Kira — each begin their gender transition, supported in different ways by their families. This deeply sensitive documentary follows them between ages 15 and 17 as they navigate the emotional and physical challenges of being transgender. For them, puberty brings intense distress, as their developing bodies do not align with their true gender identity. The film explores the difficult questions faced by parents and doctors: whether to medically delay puberty, start hormonal treatment, or wait and risk worsening the teens’ suffering. Through moments of doubt, upheaval and hope, the documentary offers an intimate look at three young people who want only one thing — for the outside world to see them as they know themselves to be.

Despite the efforts made in recent decades to protect wildlife, the loss of biodiversity in Europe remains alarming. What can be done to protect it? While some advocate "letting nature take its course", the work of numerous ecologists and researchers runs counter to preconceived ideas: according to them, the protection of endangered species often requires, on the contrary, human intervention - provided that it is reasoned and respectful of the environment. Leaving land uncultivated can be counter-productive, as in the case of the Chizé forest in the Nouvelle-Aquitaine region of France, where the cessation of tree-cutting has driven away several species of snake that previously thrived there.
