Watch Sadisflix. In the summer of 1969, four friends built a raft to travel down two Portuguese rivers from the center of the country to Lisbon. Forty years later, the son of one of these men reported this event in a book of poems, as a metaphor of the Portuguese travel literature of the 16Th and 17Th centuries. After, it occurred to him to turn the poems into a real event, to invite some friends to reenact the raft journey and exhibit texts from those peregrinations. His brother went along to film the floating recital.
