Param Sundari plays out like a quintessential Bollywood take on the North-South romance, where Punjabi beats echo in Kerala's coconut groves. At its heart is Sundari (Janhvi Kapoor), who runs a quaint homestay in God's Own Country, burdened by grief after losing her parents and exhausted from single-handedly managing their legacy. She's supported by the village elder (Renji Panicker), the community, and her younger sister (Inayat Varma), yet she carries an unshakable emotional void.
