Waves is inspired by a short novel of Robert Louis Stevenson, The Ebb-tide, written and published in 1894, the year of his untimely death (Stevenson was 44 years old).
Davide and Loris are brothers and live in a very small village in the north of Italy. While Davide is eighteen years old and gay, Loris is almost thirty and doesn't know anything about his brother's sexuality.
