Just off the busy A-2 highway in Hannover, Germany the Domina Files film crew was invited to visit Institut IMS, a true BDSM gem where Miss Alexa submits one of the house slaves to an extensive session, where neither rope nor the whips are spared. The treatment includes a medical examination, nipple play, CBT and total enclosure in a latex vacuum bed. Complete with interview segments with Lady Sandra, owner of Institut für Innovativen Masochismus & Sadismus (IMS), a dungeon tour and behind the scenes footage of the city of Hannover in Germany.
