I theia mou, i hipissa (1970)

To avoid a complicated truth and sustain an innocent fabrication, Leni--a middle-aged widow and a hard-working hotel cleaner--accepts the help of the friend and affluent tenant, Stefanos, when her young daughter who studies abroad, Catherine, suddenly pays a visit. Accompanied by her future father-in-law--the extremely rich Greek expatriate, Pete--and his free-spirited flower-child son, Johnny, Catherine is utterly oblivious of her mother's little scheme; however, a drastic and mutual decision will drag Leni and her team of amateur investigators deep into Matala--a happy and freewheeling commune of non-conformists in Crete. But, can the intruders blend in with the community? Will Stefanos' undercover hippie aunt manage to talk some sense into her radical child?
