Five young men participate in an experiment drug test, which is known as a short-term, high-paying part-time job.
Minoru is diagnosed with cancer and undergoes surgery, but it is soon discovered that the cancer has spread to his lymphatic system and he is prescribed anti-cancer drugs. He is soon plagued by severe side effects such as vomiting, skin rash, and hematuria, and begins to distrust hospitals.
Minoru falls ill with a heart ailment, but luckily finds a donor and undergoes a transplant. However, after he has married his co-worker and had a child, he discovers that the blood infusion received during his transplant was contaminated with HIV.
