After his best friend dies by suicide, Jan leaves Belfast and returns to Catalonia, where he grew up. He travels with Laura, his ex-girlfriend, to their coastal hometown for the funeral. During the journey, their restrained conversations gradually bring old memories to the surface and expose the unresolved fracture that ended their relationship.

The supplied synopsis places the emphasis on the emotional consequences of returning home rather than on external plot developments. The funeral acts as the immediate reason for the trip, while the drive gives Jan and Laura space to reckon with what remains unsettled between them.
