With her dad elsewhere on business, Gidget (Sally Field) spends the weekend with her sister Anne (Betty Conner) and brother-in-law John (Peter Deuel). Reasoning that this set-up should not interfere with her social life, Gidget asks for and receives permission to go out of town with her friends. Little does our heroine know that her trail is being dogged every inch of the way by a secret chaperone. Watch for a young Barbara Hershey as Ellen. ~ Hal Erickson, Rovi
