Overview:

Kuttikrishnan (Jagadish), the illicit son of businessman Ananthan Nambiar, comes to Kochi to meet his dad, but a mix-up leaves him on the streets & another young man, Balagopalan (Mukesh), in his place as Nambiar's son. To expose Balagopalan, Kuttikrishnan teams up with cutpurse Mukundan (Jagathi) & car-thief Meenakshi (Annie), both of whom ensconce themselves in Nambiar's house as Kuttikrishnan's relatives. Meanwhile, Nambiar's manager Krishnadas was plotting to usurp Nambiar's assets.
