Lt. Reg Barclay (
Dwight Schultz), the hypersensitive crew member introduced in the third-season episode "Hollow Pursuits," is the focus of attention in this fourth-season installment. On this tour of duty, the shy, withdrawn Barclay is suddenly endowed with super-human intellegence. Testing his new mental skills, he interfaces with the
Enterprise's computer, whereupon the starship is hurtled deep into uncharted space. Joe Menosky wrote the script for "Nth Degree," which originally aired April 6, 1991. ~ Hal Erickson, All Movie Guide
