Riordan and Cassandra Rane are a young brother and sister (24,22) that share a small apartment on the lower east side of New York. Cassandra is forced to live with her brother because she was in a crippling car accident and can't walk very well. Rio doesn't mind, and helps her without question.

Hyperion, their older brother, (26) works as a medical technician in Pennsylvania, employed with their uncle. He wants to see them more but he doesn't have the time.

Now that he has returned, what happened? And why is he there to stay?
