Amara and Chloe are monozygotic twins who were separated at infancy and raised by different families in different countries. As adults, they meet and find they have very different attitudes towards risk. Amara is a thrill-seeker who frequently participates in extreme sports like skydiving, whereas Chloe is extremely risk-averse, preferring predictable and secure routines.
