Karisma Kapoor's comeback film is turning out to be a film from a completely different league. Vikram Bhatt's 'Dangerous Ishq' is going to be the biggest challenge of the actress' career. Karisma will play five different roles across five different lifetimes covering various events; spanning from the ancient spiritual times to the partition of India, assassination of ex-prime minister Indira Gandhi to present day politics. Not only this she has to train herself in martial arts too.
