Dr. Sara Tancredi, having left the prison infirmary door unlocked (as Michael asked), realizes she was used. She finds the paper crane Michael left her with the message: “There’s a plan to make all of this right.” She hears the escape news on the radio, looks at the crane, and cries — then she is shown later overdosing in her apartment (the last shot of the episode).
The episode begins with Michael, Lincoln, and the rest of the group trying to evade capture while making their way to Mexico. However, their freedom is short-lived as they soon realize that the authorities are closing in on them. prison break season 1 episode 22
