In BEVERLY HILLS CHIHUAHUA a spoiled pet Chihuahua is swept away from her comfortable 90210 existence, when the impulsive niece (Piper Perabo) of her wealthy owner (Jamie Lee Curtis) combines dog-sitting with a vacation in Mexico. When Chloe gets lost south of the border, her scrappy Chihuahua admirer, Papi, embarks on a mission to bring her back home.

UNDERDOG features the voice of Jason Lee as the titular dog, who becomes the joke of the K-9 police force after his weakness for ham disrupts a public ceremony. Dejectedly, he lets himself get abducted for an animal experiment by a mad scientist, Dr. Simon Barsinister (Peter Dinklage). He escapes, doused in experimental chemicals, to become a dog with 80 times his normal strength.
