While four beautiful friends -- Joanne (Emma Roberts), Cassandra (Tamsin Egerton), Shannon (Ophelia Lovibond) and Kerrys (Shanika Warren-Markland) -- hang out at a restaurant, they inadvertently get roped into a crime caper. Circumstances find the girls in the orbit of hapless jewel thief Dillon (Adam Deacon) and his stash of stolen diamonds, with the drama following each of the young women, even shifting across the pond from London to New York City.
