Love: a risk. Life: a gamble. Together, Marion and Art Fowler travel to Niagara Falls, where they also spent their honeymoon thirty years ago. In their luggage is their remaining cash. They exchange the money for chips and check into a wedding suite at a casino. Unemployed and in debt, they have nothing left to lose. Their marriage, undermined by infidelities, is on the brink of collapse. So they grasp at the last straw: sightseeing during the day, but mainly at the casino in the evenings. They play and bet everything on one card.
