She serves six years in prison before being paroled to Travis' parole house, and emerges bent on finding her husband and son so as to take her revenge on the former and rescue the latter. But with Libby breaking a few rules to seek revenge, Travis is after her on a long journey. She eventually finds out that her best friend, Angela Green (the women for which Nick was having an affair with and helped with the fake murder) was killed in an explosion. But all that Libby wants is to find and revenge her husband and return to her son. Libby encounters and recognizes Nick in a bachelor auction and buys him. He then lies to her telling her that he did it for insurance and he never thought that they would convict her, but she doesn't believe him.
Nick then pays a little boy for Libby to chase in a cemetery, believing that it was her son, after losing the boy, Nick hits her head on a pole knocking her out. Libby wakes up in a coffin confused next to a dead body but easily escapes by shooting the bolts holding the coffin shut. After a while, Travis becomes suspicious of Nick and he and Libby work out a plan for Nick to serve years in prison like she did, they plan a false murder of Libby with evidence and everything so it will look like Nick burned her. But with the quick thinking of Nick, the tables are turned and Travis is shot in the arm, but Libby grabs hold of a gun a shoots Nick twice by surprise. She is not convicted because you can not be convicted twice for murdering the same person. Travis then convinces her to go and reunite with her son at his school and all is at peace.

While this makes for good drama, all three characters are completely wrong. Double jeopardy only applies to a single set of facts (a single incident)—a fact that renowned Harvard Professor Alan Dershowitz pointed out, in response to this film, as he had been using a very similar scenario in his law classes. Just as it would be two separate offenses (and two separate permissible prosecutions) to steal from someone on two separate occasions, so it would be two separate offenses to murder someone twice. (although as it ultimately plays out, Libby's actual murder of Nick could be ruled as Self Defense) Not only could Libby be charged with murdering her husband a second time, there are a whole host of other crimes she commits during the movie for which she could be charged. Moreover, a parole board can revoke parole based on new information without violating double jeopardy, since parole is not a constitutional right.
