There are two stories in this video:
In the first, Becca, Ashley, and Gina are enjoying a brief time together away from the office. Soon, however, they are chloroformed one-by-one by an escaped maniac. He then ties their unconscious bodies (one by one) to chairs. When theyh come to, they struggle to free themselves while the maniac looks on. Eventually, he chloroforms them again.
In the second, Batgirl (Gina) and Robyn (Becca) set off to find a criminal in the woods. The villainess (Ashley) chloroforms Batgirl and Robyn. They awaken tied together. When they come to, Ashley reveals herself as the villain and chloroforms them again. After a nice unscheduled nap, Batgirl and Robyn struggle against their ties and eventually get free. They chase after Evil Ashley. When they catch her, they turn the tables, chloroform her, tie her up, and stand in victory over the defeated villainess.
