Sin Nombre (2009) Review: Fleeing North on the Train Roofs

Is Sin Nombre worth watching?

Yes. Sin Nombre is a taut, heartbreaking thriller about the journey north through Mexico, and one of the most assured feature debuts of its decade. Cary Joji Fukunaga combines the momentum of a chase film with an almost documentary attention to the lives of migrants and gang members, and the result is both exciting and humane. The reservation is that its plotting sometimes leans on familiar genre beats, and its violence, though never gratuitous, is hard to watch.

What is Sin Nombre about?

Sin Nombre follows two young people whose paths cross on the roof of a freight train. Sayra (Paulina Gaitán) is a Honduran teenager travelling with relatives, hoping to cross Mexico and reach the United States. Willy, known as Casper (Edgar Flores), is a member of the Mara Salvatrucha gang in southern Mexico, living a double life between gang loyalty and a secret relationship.

When Casper’s life with the gang breaks apart, he ends up on the same train as Sayra, heading north with his former brothers in pursuit. Kristyan Ferrer plays Smiley, a young boy being initiated into the gang, whose story runs alongside theirs.

Fukunaga wrote and directed the film, his first feature. It is in Spanish, set and shot in Mexico, and runs 96 minutes.

A chase film on the roof of the world

The train journey is the film’s great setting. Migrants cling to the roofs of freight cars for days, exposed to heat, rain, bandits and police, and Fukunaga and cinematographer Adriano Goldman capture that world with a vivid, restless camera. The landscapes of southern and central Mexico are beautiful and threatening at once, and the constant movement of the train gives the story an unstoppable forward pull.

Fukunaga also knows how to build suspense. The threat of the gang, always a step behind, turns each stop into a potential danger, and the film’s pacing is tight enough that its 96 minutes pass quickly.

Gang life without glamour

What distinguishes Sin Nombre from a standard thriller is its unsentimental portrait of the gang. Fukunaga researched the Mara Salvatrucha closely, and the film shows its rituals, its hierarchies and its brutal initiation of children in a matter-of-fact style that makes it more disturbing than any stylised violence could. Smiley’s storyline, in particular, shows how the gang offers belonging to boys with nowhere else to go, and at what cost.

Edgar Flores gives Casper a quiet, haunted quality; he is a young man trying to escape a life he chose too early. Paulina Gaitán brings resilience and curiosity to Sayra, and the tentative bond between them is handled with restraint, never becoming a conventional romance. Kristyan Ferrer is chilling and sad as a child learning to become a killer.

Where genre takes over

For all its realism, the film is structured as a chase thriller, and at times the conventions show. Some coincidences feel convenient, and Sayra is written with less depth than Casper, so her perspective on the journey is sometimes sidelined. The film’s view of the gang, while grounded, can also slide toward melodrama in its confrontations. These are small flaws in a film this confident, but they keep it just short of a masterpiece.

Who should watch Sin Nombre?

It is essential for viewers interested in migration stories, Latin American cinema and gritty crime dramas, and for fans of Fukunaga’s later work who want to see where his style began. It is short and intense. There is strong gang violence, including against children, as well as a sexual assault threat and killings; it is strictly for adults and mature older teenagers.

Three Mexican films that pair well with it:

• Amores Perros, another raw, urgent story of violence and survival that helped define modern Mexican cinema.
• Y Tu Mamá También, a very different road movie through Mexico that also looks at the country’s inequality from the roadside.
• Roma, a gentler, deeply observed portrait of lives shaped by class and circumstance.

The verdict

Sin Nombre is a gripping, compassionate and beautifully crafted debut that captures the dangers of the migrant journey and the lure of the gangs with rare clarity. Its genre mechanics occasionally show through, but its power, performances and images make it essential viewing.

Rating: 4.5/5
