Martha is eagerly anticipating the visit of the Careers Guidance Counsellor, Mrs Lazarus. It's the perfect opportunity to help her finally decide upon a future career.

When the mean-spirited Mrs Lazarus suggests Martha may not have what it takes to become a human rights lawyer and tells her to 'aim lower', a defiant Martha sets about proving her wrong.

Jas is upset that the school snack vending machine has now been designated for the use of sixth formers only. Martha sees this as a perfect opportunity to prove to Mrs Lazarus just what she can achieve.

Encouraged by her Mother, Martha sets out to prove it's an infringement of Jas's human rights to deny her access to her favourite snacks. She lobbies for a meeting with the school governors, only to find herself pitted against her own mother, who happens to be chair of the governors.

As mother and daughter prepare to battle it out, Mrs Fitzgerald tells her daughter 'blood is thicker than water, but justice is thicker than blood'!

Martha wins the day and defeats her mother, who storms off. Minutes later it's revealed that rather than being cross her mother is actually very proud of Martha and heartily congratulates her, calling her a chip off the old block!
