When Bex gets an audition for The Tingle Factor, she begs geeky guitarist Matthew to accompany her, hoping he'll lift her performance. But the judges want Matthew – not Bex! Bex swallows her envy, and persuades a reluctant Matthew to take part by offering to help with his family. While Matthew gets swept up in the world of reality TV, it's Bex who has to deal with his sweet, affection-starved sister and his angry disabled mother.
