Synopsis
A man is shown in his kitchen making a sandwich and dancing, when his wife returns home, it is revealed that he is suffering from a mysterious condition that causes him to dance uncontrollably and reproduce the same jittery movements in a loop. His wife drives him to the hospital where a doctor is unable to diagnose him, and his condition causes him to get in trouble both at work and with his family. The doctor prescribes the wife medication which the man refuses (or is unable to) take, and eventually the doctor reveals that the man's condition will soon be fatal. At the man's funeral, as the funeral attendants kiss the man's forehead in respect, the doctor realizes much too late that the condition is contagious through physical touch, and rushes to warn them only to discover he is too late, and that the funeral attendants have also begun dancing, as he himself begins to succumb to the illness.
