Lily, Martha and Jas are smart but socially awkward girls trying to make sense of life, boys and fitting in. When her heroine Jade gives an emotional slide show in assembly promoting a Save the Hedgehogs campaign, Martha becomes troubled - she's the only person not reduced to tears and worries there is something wrong with her. She and her similarly un-emotional mother embark on a journey to find out how to cry. Meanwhile, Matt learns to play the guitar, so he can audition to be part of cool girl Scarlet's band.
