It's late August, and Kyle Edwards is landing at Burlington International Airport to undertake his new teaching assignment at St. Mark's College. There he meets the comely Charlotte "Charlie" Borden, a history professor and assistant coach of the equestrian team.
When Charlie invites Kyle to the ranch for winter break, she becomes involved in a serious accident. After her recovery, she displays her ability with horses and weapons nurtured by her long-time friendship with the nearby Native American tribe.
At St. Mark's, the Dean askes Charlie to chaperone four students on the annual wilderness trip to the school's cabin. She is allowed to bring Kyle.
While at the cabin, very late at night, a private airplane crashes while carrying drugs from Canada to the U.S. Hank Rivers, the main bad guy, and his crew take over the cabin and forbid Charlie from leaving. However, she manages to capture a wild horse, going on a daring escape.
Charlie uses her skills to overcome the bad guys, and must do everything in her power, to avoid being captured. She ultimately prevails, but an interrogation comes down to a false allegation and the bad guy's testimony against hers.
To prove her case, Charlie devises a plan to surveil Hank and the pilot to catch them in the act. The question is, will Charlie clear her name and prove her innocence?
