Ex cop turned lineman overhears a phone call in which a woman hires a contract killer to take care of her sister. With the help of his cop friend, the lineman tries to determine which of the two gorgeous sisters has murder on her mind.

When telephone repairman and ex-cop Bruce overhears a potentially deadly business conversation over crossed wires, he dutifully reports his concern to his police-detective pal, and former brother-in-law, Roy Walker. Bruce believes that one of two sisters--realtor Susan Sternam and exotic dancer Rachel Sternam--has hired a hitman to eliminate the other. Playing the good citizen against Roy's advice, Bruce confronts both women.
