All the beloved characters from the classic raunchy teen comedy "American Pie" are back! A little over a decade later, the sex-obsessed classmates are together again for their high school reunion, and in one long overdue weekend, they discover what has changed, who hasn't, and that time and distance can't break the bonds of friendship. Their virginity may be a distant memory, but the laughs are as loud as they were "back in the day."
