Final answer:
The question seems to be related to a text involving a 'Robinson case', possibly referencing the literary work 'To Kill a Mockingbird'. It asks for further information on the case and Atticus's plan, which in the context of Harper Lee's novel would be his commitment to defending Tom Robinson.
Step-by-step explanation:
The question appears to relate to a literature class, focusing on a case or situation within a text that is likely thematic or narrative in nature. Without specific information about the Robinson case, it's challenging to provide a direct answer. Atticus's plan, however, if in reference to the character from Harper Lee's To Kill a Mockingbird, is to provide a robust defense for Tom Robinson despite the racial prejudices of the time, as it's his moral and legal duty. To conclude a chapter on the Robinson case, further information would typically detail the final events or a summary of the case's resolution, and Atticus's plan might involve an appeal or a strategy for ensuring justice is served.
