A five-year-old named Grace creates an imaginary friend, because her parents only pay attention to the new baby, Tony. Now at 35, his sole friend reappears to help her.

With the occasion all but overshadowed by her sister's upcoming wedding, angst-ridden Samantha faces her 16th birthday with typical adolescent dread. Samantha pines for studly older boy Jake, but worries that her chastity will be a turnoff for the popular senior. Meanwhile, she must constantly rebuff the affections of nerdy Ted, who is unfortunately the only boy in school who seems to take an interest in her.
