Over three decades ago, Abigail embarked on an intense affair with Mads, the father of the family she lived with in Denmark during her gap year in 1987. What will happen when she attends his funeral now?

Return to Silkeborg weaves back and forth between the present day and the events that occurred during this gap year. Abigail must revisit her past and try to come to terms with the twenty-three-year age difference and the clandestine nature of their relationship. She no longer views it with rose-coloured glasses; now she has a teenage daughter. What unfolds is a journey of self-discovery and reflection as Abigail confronts the truth of their connection.
