Lady Ramboh finds her sister and her best friend on vacation, and the three of them spend the days having lots of fun. But the fun trip is ruined, when the girls are kidnapped and raped by the remaining traffickers. Lady Ramboh seeks revenge. She has a room full of grenade launchers to prove it.

Another buxom bombshell falls prey to the masked vigilante, the Big Boobs Buster!

Now, the spurned woman gets even by donning a ridiculous costume and taunting her well-endowed nemeses. Will bouncy coeds across the land be forced under cover? Is any bosomy beauty safe from the Big Boobs Buster?
