On a night out, a young soldier tries to improve his chances with an attractive woman by courting her grumpy sister. 

But when Isaac playfully pulls Edith off a bench, she slumps limply to the floor. Only now does he discover her wheelchair parked on the side. 

The next morning, he is ashamed of the incident and is determined to correct the sisters' image of him. An unexpected friendship soon develops between Edith and Isaac. But her growing mistrust and his obsession with curing her lead to a frenzied whirlwind that drags everyone into disaster. 

Loosely based on Stefan Zweig's 1939 novel Beware of Pity.
