Billie (Maisie Richardson-Sellers) is suffering from blackouts and memory loss - perhaps the first troubling signs of inheriting her mother's dementia. Her girlfriend Alex (Shannon Woodward) assures her that she is safe and not to worry but Billie cannot escape a nagging sense of unease and deja vu every time she regains consciousness. As disorientation intensifies and Billie wonders of she might be losing her mind, her friend Kim (Kate Szekely) suggests an alternative theory that might be linked to her alarming current predicament and the disappearance of an old flame (Rosaline Elbay)
