There she has vivid visions of the life of aspiring 60s singer Sandie (Anya Taylor-Joy) who is everything Ellie is not.
At first this gives Ellie inspiration and confidence she lacks, but then things start to turn sour, for Ellie has always been 'sensitive' and she can't switch these visions off. Every night she must live Sandie's life.
No good will come of this.
Edgar Wright does a love/hate letter to 60s Soho in all its glamour and seediness with a time travel/body swap supernatural mystery.
By day Ellie struggles to cope with whatever it was she saw last night in Soho. At night she's sometimes an observer, sometimes a passenger and sometimes maybe can lay a hand on the wheel.
Past and present start to collide putting her new life at risk until it builds to a great conclusion. It's long but needs the time to build momentum.
Really good stuff from the two leads and Matt Smith is fun as Sandie's gangstery "manager". The soundtrack is fantastic and I'm a sucker for 60s period pieces.
Recommended, 8/10. Only really let down by the last scene, but then I know why they added it.
