Jack plot
"Jack Powell is about to tackle his biggest adventure ever... the fifth grade!"
A birth with a witch (Diane Lane) as mother and a tin man (Brian Kerwin) as watching father (both quickly departed from a costume ball) should produce a special child. So is little Jack (Robin Williams). Although, small... The infant is growing at breakneck speed. When Jack celebrates his first birthday, he looks like a toddler and at the age of four he has to shave. Jack has a unique growth problem: he ages four times faster than any other human.
