Between documentary and animation, this film delves into collective memory, rescuing ancestral symbols and reopening old questions: what future remains when we forget the past? Profundo is born to inspire—to remind us that each whale carries the history of the planet, that each sea holds what we have not yet been able to protect. It is an urgent, sensitive, and visually intimate appeal that invites us to see the ocean as a living, sacred, and vulnerable territory.

Tardigrades, also known as water bears, are microscopic animals famous for their incredible ability to survive extreme conditions. Despite their funny appearance and slow, bear-like movements, they are among the most resilient creatures on Earth. They can withstand extremely high and low temperatures, enormous pressure, toxic substances, and even high levels of radiation. This documentary explores the secrets behind their remarkable survival abilities and explains how these tiny creatures have developed such extraordinary “superpowers.” Combining scientific information with humor, the documentary also looks at what we might learn from tardigrades and how their unique abilities could have potential applications in the future.
