Going after a corporation whose agricultural division was responsible for the illnesses and deaths of children, Nate, Sophie, Eliot, and Parker board a flight at the last minute looking for evidence of the cover-up. They discover the corporation's CEO intends to take out not only the accountant who found the evidence (Sara Rue) but the entire flight with her.
Eight episodes in, the cast has officially gelled. Each character has shining moments, and together their timing clicks. Kudos to writer-producer Amy Berg.
Co-creator John Rogers has an excellent blog post on how episodes of Leverage are conceived.
