The film follows the aquatic adventures of Lino, an adventurer, tireless and courageous explorer, who takes us on a discovery of the underwater seabed and some unknown and symbolic places of the southwestern coast of Sardinia. Lino’s tale will also explore the depths of the human soul, telling what steps need to be taken in integrating and involving all categories of people in sports and adventure activities. The story of his life, before and after the accident that deprived him of a leg, becomes a metaphor for overcoming the mental and physical limits of human beings, in the journey of self-knowledge, and in confrontation with the wild immensity of unchallenged nature.
