 Nevada police take into custody drifter Mark Jonah (Wayne Newton), although he claims he was an innocent hitchhiker, after the crash of a stolen car in which hoodlum Jerry Taggart (Sal Mineo)is killed. Mark escapes and, while sleeping in a field two days later, is awakened when an eight-year-old blind girl, Nina (Lilly Martens), stumbles over him. Nina leads Mark to three other blind children---Kim (Erin Moran), Little Joe (Brandon Cruz) and Cathy (Michele Tobin). The youngster s, sensing Mark s gentleness, take him to their summer camp for blind children. There, he meets Tracy (Diana Ewing), a girl his own age who is also blind. He is mistaken for the camp s new handyman by Tracy s housekeeper, Nonna (Jo Van Fleet), who views him with suspicion, and also meets the other children, Richard (Teddy Quinn), Velma (Susan Mathews) and Pepe (Ira Angustain.) The children learn to love Mark, whom they follow everywhere, as their Pied Piper figure. Led by tough Barney Glover (Keenan Wynn), the police finally catch up to Jonah. But a well-known local character, Wilfred Bashford (Mickey Rooney), clears Mark, who returns to Tracy and his new "family."
