It's Eve's first Christmas and after finding a way to connect to her mother, she has a million questions in her mind. She contacts Mary Douglas, but instead of answers, she contracts a software virus which activates her latent ability to dream. When Will finds Eve in an unresponsive state he works tirelessly with Nick, Lily and Katherine to figure out what's wrong with her. They get a window into Eve's dream state, but Eve's brain wasn't wired to cope with imaginative visions and it's behaving weirdly. The software virus sends Eve into a cheerless parallel world, and as Eve can't distinguish between reality and dream, her systems start to shut down. Can Will and the gang save Eve from her Christmas nightmare? And can Abe escape his own nightmare - being 'Santa's little helper', dressed as a Christmas elf?
