Set in the 1940's, Rivers Never Fill The Sea follows the lives of two families; the Masons and the Brennans. Mike Mason is a rapacious land developer in the coastal town of Woodrose, California. Hostility begins when Mason buys out a home belonging to former boxer, Ty Brennan, forcing the eviction of his family. The animosity between the two of them grows further when Ty's son and Mike's daughter fall in love, complicating matters. A gambling ship off shore, a dangerous and covert operation that carries a heavy consequence, and a devastating cyclone all come together one fateful summer and nothing would ever be the same.
