Knot Agents (1999)

An inexperienced agent is sent on a mission to infiltrate the lair of a enemy agent known only as "Stef". The agent believes her mission is only part of her training and the buxom blonde she has captured is an experienced agent in on the assignment. When both women are captured by the enemy spy, the rookie agent has plenty of time to contemplate her many blunders while securely roped, tied and awaiting rescue.
