Cheri and the Pirates(1988)

Overview

Suspecting that her sister has been abducted by human traffickers, Serena recruits an inexperienced but lovely operative to help her board a yacht belonging to Salazar, a reputed mobster, and rescue the innocent ingenue. This hour long bondage cheapie with barely even any nudity is saved by a hilarious performance from Michelle Bauer as Lotta, the maniacal white slaver's assistant.
