A dog with a plan adopts a chaotic family in a wry comedy extolling the virtues of common sense.
When Ma Peachey takes up yoga, the rest of the family finds themselves abandoned to chaos: no one cooks dinner, no one picks up the dirty laundry, the children are always late for school, and there is a good deal of squabbling and squalor. Ma may be off finding inner peace, but irritable Pa Peachey, glum Ava, and wannabe girl-charmer Ollie are falling apart. Only Betty, the sensible youngest child, is wise enough to see that this family is in need of rescue. Enter McTavish, a rescue dog who, true to his mission, is ready to teach this family some new tricks. Getting the Peacheys to behave will take work, but if anyone can do it, McTavish can. After all, he's a very good dog — maybe even a psychological mastermind!
