Lawyers, Alina and Jarin meet while on a white water rafting trip. They survive being tossed from a raft and over a waterfall and manage to reach a bush hut just before a storm arrives. Their lives become closer but dangers lurk everywhere.

Silverstone Law where Alina works has a devious hidden agenda and corrupt leaders.  Jarin, is the owner of a small law firmwith mainly family law clients.
