The movie revolves around the story of a small-time spice business owner, Raju (played by Rajesh Khattar), who gets into a rivalry with a big-time spice business tycoon, Taawla (played by Aushima Soni). The story takes a turn when Raju's wife, Sharmila (played by Raveena Tandon), gets involved in the business, and they come up with a plan to take down Taawla.

Aarti Gupta plays the role of Nikki, a supporting character in the movie. Unfortunately, I couldn't find more detailed information about her specific role or impact on the plot.

After conducting research, I found that Rocco ( likely Rocco DeLuca, an Indian film actor) has a supporting role in "Garam Mirchi" as well. However, I couldn't find more specific information about his character or screen time.

"Garam Mirchi" is a 2005 Indian comedy film directed by K. Ravi Shankar and produced by Sanjay Dutt and Siddiqui. The movie stars Raveena Tandon, Rajesh Khattar, and Aarti Gupta in leading roles.

"Garam Mirchi" received mixed reviews from critics but performed moderately well at the box office. The movie is remembered for its light-hearted comedy and Raveena Tandon's performance.
