Driving from Portland to Los Angeles, where Laura plans to deposit Jack in the home of her sister, the goofy Deadhead and dog - walker JoJo (Kriste Schaal), they stop off at the homes of several key people: Jack's two old buddies, played by a warmly flaky Christopher Lloyd and a coolly flaky Peter Fonda, as well as Laura's ex-husband, a
flyweight scoundrel (Bobby Cannavale) whom she married
because he was her dad all over again.
