Becky soon becomes attached to a group of boys at the campsite and takes a shine to one in particular. But, when Roy wants to join in, Becky thinks her younger brother is cramping her style. Things come to a head when her new-found friends prefer Roy's company to hers and she is left simmering on her own.

Soon Roy's new crowd reveal their true nature and leave him in the lurch. Will Becky be able to forgive her brother and come to his rescue?
