Shooting in South Africa should be loads of fun but "Woh Lamhe" actress Kangana Ranaut is eager to return home to be with her sister, who received serious burn injuries after two men flung acid on her.

"The country is so breathtakingly beautiful, filled with natural beauty but my heart is just not in it," Kangana told IANS.

She is shooting for Suneel Darshan's "Shakalaka Boom Boom" with Upen Patel.

"We're doing a song. And it's like a party. We shot it in a goldmine. Upen is great fun. And, my god, he talks so much! Before he completes one topic he runs on to the next.

"But I want to return home. My sister Rangoli is in the hospital. Of course, my parents are there to look after her. But without me they're a little lost in Mumbai."

There's an added pressure on Kangana to return home.

"My sister is supposed to undergo skin grafting for her burns in a couple of days. I really need to be near her. I don't want to delay the operation. Rangoli wants to look as pretty as she did earlier for her wedding, which is on Feb 8. We really can't delay her cosmetic surgery."

Kangana feels the acid-throwing accident could've done worse damage to her sister.

"Her face could've been irreparably damaged. Her fiancé could've called off the marriage. None of this happened."

Kangana, a thorough professional, will not leave if it creates problems for Darshan.

"If Mr. Darshan asks me to stay back, I will. But I'd really not like to miss my sister's surgery. And there's no way I'd allow her to be operated until I'm present."

Now the matter has been sorted out. Kangana returns home for the operation in the first week of November.

"She's expected to completely recover. After the acid throwing, anything could've happened.

"Maybe some people don't like the fact that a small town girl like me is being noticed so suddenly. I want to make it clear that I'm not here to be a threat to anyone. But I won't take insults or injustice lying down. God has been kind. My sister has got back her life. That's more important to me than any success."

Police arrested both the men in the Himachal Pradesh town of Mandi last week.
