Solving crimes in the 1970’s wasn’t an easy task, but Detective Mark Wilder was the heartbeat of the Dallas PD, and murder was his specialty. When a body washes up on the banks of the Trinity River during a torrential rainstorm, all evidence gets washed away. Likewise, when other dead bodies are discovered at two other lakes in Dallas, rain curses the crime scenes. So, what does a clergyman, a drug dealer, a beautiful woman, and the rain have in common? Could it be the Rain Man? Maybe, maybe not - crime has no conscience.
