Sunaina made her debut as heroine in the film Kadhalil Vizhundhen. After this she acted in Maasilamani. Now she is acting in a film titled Yathumagi which has been produced BY Chozha Productions.
It was planned to shoot a song sequence in Bangkok. The hero Sachin, the heroine Sunaina, director Balakumar, cinematographer Muhammad Naseer, producer Chozha Ponnurangam along with his two daughters flew to Bangkok.
The song sequence with the line Yaro Yaro was to be shot in an island called No Man Island which is situated 30 kms away from Bangkok. The crew went to this island in three boats. The shooting also was taking place in the island.
The guides who had accompanied the crew had warned them not to shoot after 4 pm. But the crew was not bothered about the warning continued the shooting till 6 PM. After completing the shooting crew left in two boats. Hero Sachin, heroine Sunaina, director Balakumar and producer along with his two daughters boarded another boat after much delay.All of a sudden there was heavy rain.
The person who steered the boat did not know the way because of the heavy rain and poor visibility. Finally he was able to spot some lights on the shore, so he tried to reach the shores as fast as he can. But the over speed capsized the boat.
All the members in the boat were flung into the ocean. But since they were wearing life jackets, they were able to cling to capsized boats. Fortunately they were saved by a person who was passing that side in another boat. Sunaina says that she was saved because of the God’s grace.
