A wounded RAF pilot, confined to a wheelchair, is committed to an eerie hospital where he starts to lose his mind.

In World War II, Airman Toby Jugg is hit in the spine during a mission and he becomes a paraplegic. His aunt-in-law Julia Jugg is his only relative and sends him to rest at a clinic in the countryside. Toby is in love with Julia and writes several letters to her but she does not respond. Toby is haunted by shadows and bugs and Dr. Hal Burns, who is responsible for his treatment, complains that Toby does not share his feelings with him. One day, an intern goes to the town and brings a letter from Julia to Toby, and he finds that Dr. Burns is hiding his correspondence. When Julia is informed, she comes to the clinic to stay with Toby, who seems to be mentally ill. One night, Dr. Burns gives a razor to Toby and tells him to do the right thing, trying to induce him to commit suicide, but late at night Toby discovers the secret of Julia and Hal.—Claudio Carvalho, Rio de Janeiro, Brazil
