Constructed from footage shot during their year-long stay in Finland, as well as family videos and photographs, the documentary offers an intimate portrayal of Konttinen's reconnection with her homeland. It captures the nuances of rediscovering familiar landscapes and traditions through the eyes of both mother and daughter.

Letters to Katja is linked to Konttinen's exhibition My Finnish Routes and is part of a series of Amber photo films, including Byker (1983), Keeping Time (1983), The Writing in the Sand (1991), Today I'm With You (2010), and Song for Billy (2016). These works collectively explore themes of community, memory, and the passage of time, reflecting Konttinen's enduring commitment to community rooted storytelling.

Sirkka-Liisa Konttinen is a Finnish-born documentary photographer who has chronicled working-class life in North East England since the late 1960s.

A co-founder of the Amber Film and Photography Collective, her acclaimed work, including Byker and Step by Step, offer significant portrayals of the lives of everyday people in the North East. In 2011 her photography was inscribed onto the UNESCO Memory of the World Register as of national significance to the UK due to her embedded practice and historically vital portrayals of local communities. In 2025 Konttinen was awarded an MBE in the 2025 New Year’s Honours list for her services to photography.
