16 years ago, 3-year-old Madeleine McCann disappeared during a stay with her parents in Portugal. Since then, multiple avenues have been explored, without any concrete results.

Under the generous sun of sunny days, a Zodiac scratches the smooth surface. On the banks, silhouettes walk with slow steps, a dog caressing in front of them.
