Jeff and his girlfriend Jenny decide to become bank-robbers.
Jenny does the actual robbing at gunpoint inside the banks while Jeff waits outside as the getaway driver. They are initially successful with a string of heists that make headlines and they become folk-heroes. Until one day their luck runs out and they get caught.
At trial, the judge condemns Jenny to ten years in prison, while Jeff gets two years. However, once they get to their respective prisons, they discover that due to a clerical error Jeff will be serving ten years and Jenny only two. Despite of her insistence, Jeff convinces Jenny to keep quiet about it.
After two years Jenny gets out and she continues to visit Jeff faithfully every month and they exchange letters and phone calls regularly for the remainder of his ten years.
Finally, after he does his time, Jeff gets out and is joyfully reunited with Jenny. They get married and move to a different state and start anew, leaving their life of crime behind. They raise a family with children and grandchildren and eventually reach old age, after having lived a happy marriage.
On their 50th wedding anniversary party, the entire family and friends are gathered. A great celebration is had, with many laughs and stories, recounting their life together.
The conversation turns to the secrets to a happy marriage. One of the guests asks Jenny why she decided to stick with Jeff while he was in prison, despite all of the hardships.
Jenny answers: "Well... you know you have found the One when you finish each other's sentences."
