Sometimes you need to get lost to find your way...

Marnie is stuck.

Stuck working alone in her London flat, stuck battling the long afternoons and a life that often feels like it's passing her by.

Michael is coming undone.

Reeling from his wife's departure, increasingly reclusive, taking himself on long, solitary walks across the moors and fells.

When a persistent mutual friend and some very English weather conspire to bring them together, Marnie and Michael suddenly find themselves alone on the most epic of walks and on the precipice of a new friendship.

But can they survive the journey?
