Abyss (2019)

The notorious cheater Linus tries to convince his sex-refusing girlfriend Susann to finally sleep with him. One day, when she gives in surprisingly quickly, she introduces the unsuspecting boyfriend to her communal family, which lives an alternative lifestyle in colorful, cloth-heavy rooms and oddish clothing. Once there, he meets the quirky but somehow lovable occurring leader Jörg and his group, which, along with Susann, consists of five other young attractive women - among them the pretty Lilly. Linus soon finds out that Jörg sees him as an intruder and that the leader is ready to defend his "harem" by all means.
