Both sponsored runners who live together in the Dolomites of Italy, the pair shares insights into what it is like to crew and support each other, first as Valmassoi tackles the Lavaredo Ultra Trail, her hometown race, as Jones crews, and then as Jones runs the Val d'Aran 100k in the Pyrenees, as Valmassoi crews. As the two race and crew, the film walks us through eight "golden rules" of crewing, including those that anyone who has crewed can well relate to, like "survive the wait." The cinematography keeps it personal and real while capturing the often hectic nature of crewing at big races.
