I do not accept there is anything wrong with me. Days before her wedding Megan discovers she has a 50-50 chance of developing early onset Alzheimer's. Years later she's offered a genetic test. But if she's got the gene does she really want to know? Megan, 21. Megan, 47. Megan, 32. Megan, 27. One woman lurches through time while her young family deal with the consequences. I can't think. But I still feel. And most of the time I feel scared. Scared because it's too soon. I haven't finished yet.
