Twenty-nine-year-old Alice Love is pregnant with her first child, adores her husband, Nick, and has never set foot inside a spinning studio. Thirty-nine-year-old Alice Love suffers a sudden fall in her Friday spin class, wakes up with a splitting headache, and finds out she has three children and is in the middle of custody proceedings. Without any concrete memories of the past 10 years, Alice tries to figure out how her free-spirited 29-year-old self became a volunteer-coordinating, spin-class-attending 39-year-old woman. What Alice Forgot is an often funny, sometimes heartrending, deeply personal portrait of a woman attempting to unravel her own mystery.
