Next of Kin (1984)

Twenty-three-year-old Peter Foster, an only child stuck at home amidst his parents' constant bickering, struggles with a sense of purpose. To address their issues, the family visits a clinic for therapy sessions captured on video. After watching his own tape, Peter becomes intrigued by the story of an Armenian family who adopted out their son upon arriving in Canada. Seeking connection, he visits the Deryans, posing as their long-lost son, Bedros. Embraced warmly, Peter takes on the challenge of mending the strained relationship between George Deryan and his daughter, Azah.
