Renowned scientist Professor Newton Jennings posits that life no more advanced than amoebas or jellyfish can exist on Mars. Martin helps Angela write a report refuting Jennings claims, which quickly gets her a failing grade. When Martin's attempts to reason with Angela's teacher, Miss Weaver, fails, Martin figures the only way to regain the upper hand and Angela's trust is to speak to Jennings and expose him as a fraud. However Jennings is brilliant but has one minor flaw in his calculation. So Martin, with Tim's help, plants a seed in Jennings brain to correct the calculation, which Martin hopes Jennings will pick up. The brilliant professor does and restates his theory, which in turn leads to vindication for both Angela and Martin. (thetvdb.com)
