Martha and Ollie's team always comes first in the school's general knowledge quiz. Lily is determined that this year she and Jas will beat Martha and Ollie. However, both Lily and Martha get the flu. Maxwell and Cassie are roped in as replacement team members for Lily and Martha, who continue to give orders from their sick beds. Jas is confident that she won't get sick because of her dad's homemade 'Salford Special' health drink. Jas and Maxwell in turn try to play on Ollie's hypochondria to gain the upper hand. Meanwhile, Mrs Griggs has decided to perform a salsa dance before the quiz with a reluctant Mr Malone as her partner. When Mrs Griggs gets the flu Ms Parfitt has to step in.
