Cavemen follows LA playboy Dean (Skylar Astin) who is fed up with one-night-stands and empty relationships and realizes that he wants something more out of life than just a party. With a little inspiration from his nine-year-old nephew and his best friend Tess (Camilla Belle), Dean decides to try his hand at finding true love for the first time - which proves to be much more difficult than he thought in modern-day Los Angeles.
