. When the Raja is shot, Kumar takes him to a nearby hospital, dons a Sikh's turban, poses as the Raja's son and goes to the private island of John. Also attending are K.P.W. Iyengar, Dr. Bukhari, Colonel Columbus, and Countess Rasmussen. A stunned Kumar finds out that all of these invitees are master criminals and gangsters. Kumar's guise does not fool anyone, including his former sweetheart, Sheila Enders, nevertheless John permits him to stay on, as he feels that Kumar's career, though an amateur, is consistent with those already present.
