The plot of the film illustrates the embankment of two friends on a quest for a lost buddy, who was once an optimistic and successful student. On their journey, they recount their college life and special moments that the three shared up until their lost friend secretly parted ways after convocation. During their quest, the two encounter a rival classmate who once made a long forgotten bet with them, a funeral that goes impossibly out of control, and a wedding they must crash.
