Quake.

Saga gets hit by a fierce epileptic attack walking in a public park with her six-year-old son resulting in a total memory loss. Afraid of being considered unable to take care of her son, Saga attempts to hide her state from others and occupies herself digging for the answers she needs from within. As she struggles to gather bits and pieces from her forgotten life, repressed memories that Saga unconsciously blocked as a child suddenly start to come back, revealing a painful truth about herself and her past.
