From the liner notes

Christopher Walken is hilarious as Nat, an eccentric con-artist and deadbeat dad dying to reconnect with his troubled son, Flynn (Alessandro Nivola, The Eye, Laurel Canyon). Diagnosed with a terminal illness, Nat shanghais his reluctant son into driving him cross-country for experimental medical treatment. Low on cash, they pull off increasingly ridiculous and embarrassing schemes along the way to reach their destination spending only $5 a day. Boasting a star-packed cast that includes Sharon Stone, Amanda Peet and Dean Cain, $5 a Day is an irresistibly fresh and charming comedy about letting go of the past and choosing your own road.
