aamrn- that's about the entire summary right there.

Ash and Misty meet in a dream that they soon find out they are sharing each night. Like a personal heaven, they also share control over their dream. Well, most control... because someone, or something, is out there watching them... their every move...

Ash is diagnosed with cancer and he tells of his life through the period of sickness. But will he survive? And in the second part, Misty tells the story through her point of view.
