As the turmoil of the modern world unravels, an aging writer, known as Senor C, is bestowed with the task of voicing his strong opinions in a collection of essays titled 'Strong Opinions.' Amidst reflecting on wide-ranging global concerns—including morality in politics, the state's role in war, and individual freedoms—his life intersects with Anya, a young woman he hires to transcribe his work. Anya's presence introduces an unexpected dynamic, as her pragmatic boyfriend Alan views the writer with suspicion and contemplates intervening. 'Diary of a Bad Year' is an homage to the power of opinion and the complex interplay between personal and political realms.
