Preteens Natasha, Gillian, CC, and Tina eagerly anticipate the end of year school barbeque, but on the night of the event, bubbly "life of the party" Tina doesn't make an appearance.

Worried by her absence, her three friends wonder if Tina is sick. Tina herself seems unwilling to provide any information, and acts nervous and upset over the phone.

When the girls uncover the truth behind Tina's "illness," they find themselves on a journey of discovery. Guided by Natasha's patient older sister, the girls learn about themselves and the women they will soon become.
