A gay couple -- one a musician, the other a novelist -- embark on a road trip as dementia starts to take hold of one of them. Sam and Tusker are traveling across England in their old RV to visit friends, family and places from their past. Since Tusker was diagnosed with dementia two years ago, their time together is the most important thing they have.

Supernova deals with the topic in a quiet and restrained manner (the British way), and along the way finds a path into your heart for these rich characters.

Featuring great performances from Colin Firth and Stanley Tucci,
