She is a painter and works in the advertising industry. Deepamol is a bubbly little girl always playing around with the telephone making random calls. One such call turns their life forever when Deepamol gets in contact with her "Telephone uncle" (Mohanlal). Deepamol gets attached to Telephone uncle very fast. Though Aleena was on the fence and skeptical of the man's intentions, she eventually falls in love. Telephone uncle resists the coercions from the mother and never reveals his name or whereabouts. Finally, he comes to their place on the night of Deepamol's birthday raising Aleena's hope for a better life, only to put an end to it within a very short time.
