Sujatha is a 1953 Sri Lankan romantic musical based on the Bollywood film Badi Bahen. It was the most successful Sri Lankan film made up to that time and started the trend of blatantly copying Indian films.
The protagonist Sujatha abandons her studies to provide for her young sister Prema after the death of their mother. Their mother had always wanted to secure a good education for Prema and Sujatha sees it fitting to make this sacrifice. When Prema heads to the city however, she is seduced and impregnated by a smooth talking womanizer named Wickie. Wickie dumps Prema who then returns to live with her older sister. They find solace in a caring doctor named Nihal who comes to fall in love with Sujatha.
