When Arvilla Holden's considerably older husband Joe dies while the two are vacationing in
Borneo, she has his remains
cremated and returns with them to their home in
Pocatello, Idaho with plans to scatter them as he wished. Joe's resentful daughter from his first marriage, Francine, demands Arvilla relinquish the ashes so they can be buried in the family
crypt in
Montecito, California and threatens to sell Arvilla's home, which was left to Francine in her father's original will, unless she cooperates. Arvilla grudgingly agrees and invites her best friends, single and lonely Margene, a former teacher who lost her job because she advocated
birth control to her students, and married Carol, a devout
Mormon, to accompany her to the memorial service. The three women drive to
Salt Lake City International Airport in Holden's refurbished 1966
Pontiac Bonneville convertible, but Arvilla decides to detour to the
Bonneville Salt Flats, a place she and Joe had visited on their
honeymoon. As they race across the flats, the top of the urn containing the ashes falls off and some of them are scattered in the wind. Arvilla decides to honor Joe's last request and scatter his ashes at other places they visited throughout their twenty-year-long marriage. This change of plans results in a
road trip that takes the women to
Bryce Canyon National Park,
Skull Valley,
Lake Powell,
Las Vegas, and the desert near
Palm Springs. During their journey they encounter Bo Douglas, a young man searching for the father he never knew, and Emmett, an aging long-distance
truck driver who has devoted his life to the road ever since his wife died, in addition to exploring their friendship and themselves as they
come of age for the second time. ==Cast==
