When a lonely and depressed Erica first met therapist Dr Tom, he offered her a challenge: if she wanted to fix her problems he could help but once committed, she couldn't back out. Erica found herself flung back into her own past with the opportunity to change the things that went wrong.

Erica's life started to go somewhere - a new job, a boyfriend. Then she lost it all...

This time Erica's able to deal with her problems, so Dr Tom is sending her on the next stage of her treatment - group therapy. In this 13 part series Erica must learn to help others as well as herself and whilst she still time-travels she doesn't always end up in her own past.
