Daunted by a never ending passing train, Ignacio can't find the inspiration to write the song he desperately needs to deliver. Seeking his muse, he canoes deep into a river kept sacred by a shaman living under a bridge. 

The deeper Ignacio ventures into wilderness, the farther away he leaves his gorilla-masked music agent Eva, who chases after him and the song he owes her. Surreal and cathartic events unravel unexpectedly, plunging him underwater, where redemption awaits him. 

Zenú intersects art and performance, exploring the relationship between nature and the human spirit.
