Marine PFC Jack Hardesty is sent overseas as part of a peace keeping mission and is seriously wounded. His childhood sweetheart, Rusty, unable to obtain news of Jack, is devastated at the prospect of life without him. Then Rusty learns of a cruel trick her father has played on her to keep them apart and she is consumed with anger. In her demented state she causes an accident which takes the lives of five people. Frightened, she flees and while resisting arrest, Rusty inadvertently cause more destruction including the deaths of two police officers. Labeled a cop killer, Rusty receives a life sentence. Soon thereafter, invalided out of the army, suffering from progressive nerve damage, Jack returns to find that the love of his life is locked away from him. During their tearful reunion in the prison, Rusty begs Jack to forget about her, but Jack vows to wait for her.

Jack finds a small house and a job near the prison and divides him time between home, prison and the nearby VA hospital because he frequently falls ill. At the hospital he meets Fran, a nurse who falls in love with him. She gives up trying for him, however, when she understands how deep is his commitment to Rusty. She and Jack fall into an easy friendship that stretches across the years.

Rusty betters herself in prison. She finishes two degrees and studies for a career. Jack, his nerve damage taking its toll, becomes more fragile. As Rusty's release date approaches, Fran arranges for Jack's neighbors, a single mother and her son to help Jack fix up his house for Rusty. Through Jack, the mother and son learn about the meaning of true love. 

When Rusty is finally released, their happiness is explosive and real, albeit brief. Diagnosed in the early stages of alzheimers, soon Jack will not even recognize the woman he loves. Already disoriented and given to wandering off, Jack goes to live at the VA hospital where Fran will take care of him and where Rusty will be his constant companion.
