Police investigate the mysterious death of a sign language interpreter. Is it related to the anonymous hook-up site he was on…or to what’s been happening between his wife and best friend?

TV weatherman Clark Forrest convinces his friend and ASL interpreter to sign up for an anonymous hook-up app to spice up his life. Floyd Smernitch is cash-strapped, overweight, and dealing with his distant wife and troubled stepson. But after joining DTF St. Louis, Floyd’s body is discovered in a pool house after a late-night rendezvous. Investigators examine Clark’s relationship with Floyd’s wife Carol, which leads to more questions about the sex lives and personalities of the suburbanites. While looking into whether friends, strangers, or lovers are behind his demise, a clearer picture of Floyd emerges: a man who longed for more than just a physical connection.
