Stri (1995)

When a man flees with a boatman's cargo the boatman confronts the woman he'd assumed was the thief's wife, who, left behind, confesses that she isn't. She was only acting as a decoy - an act, she claims, that was done from love - so he could get away with the loot, which he intends to give to his real girlfriend, a much younger, prettier girl.
