After twenty years spent on the road, gifted cellist Alex Serian returns home to Los Angeles, a family of musicians waiting for him amid all the complicated history that comes with it. Music, the one constant, all-consuming river running through his entire life, begins to carry Alex on an unexpected adventure that will change him forever, drawing together an ensemble of family, memory and creative obsession. Featuring an unusual score credited to nine separate composers, the film stands as a distinctive love letter to the music of the movies and the people who make it. A visually and sonically rich meditation on music and family, anchored by a transformative lead performance from Pedro Pascal in his first true leading film role, even as its ambitious, multi-composer structure invites comparison to a genuine cinematic experiment.
