BoJack Horseman follows the life of BoJack, a washed-up sitcom star from the 1990s struggling with depression, addiction, and his fading relevance in Hollywood. As he attempts to revive his career with a memoir, he navigates complicated relationships with his agent Princess Carolyn, slacker roommate Todd, ghostwriter Diane, and rival Mr. Peanutbutter, all while battling his self-destructive tendencies in a darkly comedic yet deeply emotional journey.
