Enduring Love (movie, 2004)

Two strangers become dangerously close after witnessing a deadly accident. On a beautiful cloudless day a young couple celebrate their reunion with a picnic. Joe has planned a postcard-perfect afternoon in the English countryside with his partner, Claire. But as Joe and Claire prepare to open a bottle of champagne, their idyll comes to an abrupt end. A hot air balloon drifts into the field, obviously in trouble. The pilot catches his leg in the anchor rope, while the only passenger, a boy, is too scared to jump down. Joe and three other men rush to secure the basket. But fate has other ideas...
