A tale of two sprinters, released – you'll never guess – in time for the Olympics.
Lenora Crichlow is pretty good as the mouthy Shania, determined to make running a way out of her low-expectation background. Lily James is frosty, middle-class Lisa, her ambition stoked by her controlling ex-athlete dad (Rupert Graves).
An immediate antagonism springs up between the two girls on being selected for the British sprint relay team. Can they put aside their ego and give teamwork a chance?
From the starting gun this is inspirational be-all-that-you-can-be stuff, low on originality but so goodhearted that you may find yourself cheering them to the finishing-line.
