Troop 458 chronicles the lives of four young girls who meet in grade school and become life-long friends. Rhonda is the tomboy, an athlete and the new girl in school. She becomes friends with Grace who is the unofficial leader. Grace introduces Rhonda to her two friends, Cassie and Peaches, and the four girls form a bond which endures throughout lives characterized by both success and disaster beginning with a tragic accident in a local park involving a classmate. Serious illness, divorce, abuse and other dramatic events test that bond...a bond which somehow stands the test of time.
