Following the school sports day, Rachel storms round with a score to settle - ranting angrily about how Samson pushed her niece Amelia.
However, Rachel's confrontational attitude leaves Sam and Lisa unimpressed and they quickly throw her out - ordering her to deal with the situation properly by contacting the headmaster.
Later, when Sam hears that Amelia has been bullying Samson over his dyslexia, he quickly realises that he'll have to fight his son's corner at the school. Will he manage to resolve the situation?
