Sam (Colin Firth) and Tusker (Stanley Tucci) have been together for twenty years. Sam is a professional pianist; Tusker is a celebrated novelist. They are also amateur stargazers — captivated by the brief, violent brilliance of supernovae, stars that burn brightest at the moment of their death.
Tusker has recently been diagnosed with early-onset dementia. His decline is gradual but irreversible.
The couple take their beloved campervan and their dog Ruby on a road trip through the English Lake District, visiting places they love, stopping to attend a party in Tusker’s honour with old friends. As the journey unfolds, both men must face what the future holds — and whether what each of them wants is the same thing.
Written and directed by Harry Macqueen, Supernova is a quiet film about an enormous grief — about love, memory, agency and what it means to hold on and to let go.
