We learn that Mila Kunis plays a character with literally all the potential in the universe, but seems to be down on her luck, and only when Chatum Tanning enters the scene does her character finally start to take off.
Here's the synopsis for Jupiter Ascending (Via ComingSoon):
Jupiter Jones (Mila Kunis) was born under a night sky, with signs predicting that she was destined for great things. Now grown, Jupiter dreams of the stars but wakes up to the cold reality of a job cleaning toilets and an endless run of bad breaks. Only when Caine (Channing Tatum), a genetically engineered ex-military hunter, arrives on Earth to track her down does Jupiter begin to glimpse the fate that has been waiting for her all along – her genetic signature marks her as next in line for an extraordinary inheritance that could alter the balance of the cosmos.
Filming has begun in the UK for Jupiter Ascending which has a July 25, 2014 release date and also stars Eddie Redmayne, Douglas Booth, Tuppence Middleton, Doona Bae, James D’Arcy, and Sean Bean.
