Nothing ever happens in Toby's small Texas town. Nothing much until this summer that's full of big changes.
It's tough for Toby when his mother leaves home to be a country singer. Toby takes it hard when his best friend Cal's older brother goes off to fight in Vietnam. Now their sleepy town is about to get a jolt with the arrival of Zachary Beaver, billed as the fattest boy in the world. Toby is in for a summer unlike any other, a summer sure to change his life.
