A TAP ON THE WINDOW
Since private investigator Cal Weaver's teenage son died in a tragic accident, Cal and his wife have drifted apart. Cal is mired in a grief he can't move past. And maybe his grief has clouded his judgment. Driving home one night, a rain-drenched girl taps on his car window and asks for a ride. He knows a grown man picking up a teenage hitchhiker is foolish - but he lets her in. Cal soon senses that something's not right with the girl or the situation. But it's too late. He's already involved.
