Dad Richard Newton (Reinhold) wants to take the family on vacation and, naturally, huge St. Bernard Beethoven is coming along. Suddenly, that rented luxury RV doesn't seem very big and dad's idea of fun is lame to the kids. Of course, it's not a typical vacation anyway, seems thieves Tommy (Ciccolini) and Bill (Marsh) need to retrieve a videotape that Richard has rented. Beethoven tries to protect his family while being blamed for every little mishap. A dog's life, indeed!
