Based on the best-selling books by Susan Meddaugh, the series follows the adventures of Martha, a loveable, honest and kind dog. When accidentally fed alphabet soup, Martha gains the power of speech and using her new skills she gets jobs, foils bad guys, wins contests, runs for office and orders lots of pizza! After TD hands in the wrong drawing in art class (a caricature of his art teacher instead of a perfectly good drawing of the back of Chuck Smith's head), he panics. With Truman and Martha keeping an eye out for the janitor, Helen and TD sneak into the school after hours to switch the drawings. But will they get caught or, worse still, eaten by a desert mountain snow wolf?
