One fine morning, things go terribly wrong for Ravi and Parvathy, with a stranger who asks for a lift in their car.

For the first few minutes, the stranger appears to be a naive mild guy, but his tone changes soon, and he begins to blackmail the couple, telling them that their daughter is kidnapped and that with just one phone call from him, the new babysitter will kill her.

The stranger also traps them in a sleazy lodge where he begins to remove Parvathy's garments but stops short of proceeding further.

In the subsequent few minutes, the audience realises that all of this was a drama plotted and enacted by Venky and Parvathy, both deeply hurt by their partners' deceit, in order to teach their spouses about the pain they themselves went through.

Even though Cocktail could not manage a bumper initial,[clarification needed] the movie picked up after a couple of days of the release.
