A new trailer for Andrew Haigh’s indie drama A Long Winter introduces a family’s tense preparations for winter in the Colorado mountains during the early 1950s. The film centers on siblings as their lives become unstable after their mother disappears, forcing them to deal with pressures and fractures beneath their home life.

Across outlets, the story is framed as an adaptation and a character-driven mystery. Deadline and other sources describe A Long Winter as based on Andrew Haigh’s adaptation of Colm Tóibín’s short story of the same name. The film is also presented as expanding from a simple premise into something more emotionally layered, with performances and period detail highlighted, including Fred Hechinger and Kit Connor in prominent roles alongside Caitríona Balfe, Ebon Moss-Bachrach, and others.

The trailer previews a setting described as remote and foreboding, with the family’s routine giving way to uncertainty as winter closes in. Film-festival appearances are noted ahead of a theatrical release in December, marking Haigh’s latest follow-up to earlier works.
