When should you trust your heart?

It's 1942 when Cassie Taylor reluctantly leaves Birmingham to become a land girl on a farm in Dorset. There she meets Robert and Stephen Denham, twins recovering from injuries sustained at Dunkirk. Cassie is instantly drawn to Stephen, but is wary of the more complex Robert - who doesn't seem to like Cassie one little bit. At first, Robert wants to sack the inexperienced city girl. But Cassie learns quickly, and Robert comes to admire her courage, finding himself deeply attracted to Cassie.

But just as their romance blossoms, he's called back into active service...
