Nelson Moss is an advertising executive caught in his daily routine, focused on climbing the corporate ladder and leading an emotionless life. However, his monotonous existence takes an unexpected turn when he meets Sara Deever, an enigmatic woman who lives life to the fullest. Sara has a peculiar philosophy: she takes a different man each month to help him find his true self. When Nelson, purely by chance, crosses her path, he finds himself swept into an unexpected journey of self-discovery.
At first, the relationship seems like a game, a fleeting adventure without commitments. But as the days go by, Nelson begins to open up emotionally and confront his own fears and insecurities. Sara, in turn, has her own secrets that torment her, and her past pursues her in ways that threaten to ruin her ephemeral joy. What started as a temporary experiment evolves into something deeper and more meaningful.
The plot unfolds in the vibrant and charming backdrop of San Francisco, where love blossoms in the most unexpected moments. As the end of the month approaches, Nelson must decide whether he is willing to risk his heart for a true connection, while Sara faces the dilemma of whether to fully open up. Ultimately, both will learn that every day counts, and sometimes true love appears when we least expect it.
