Number 99

Arthur Penryn, unjustly imprisoned for a crime that he did not commit, escapes one night in a stolen limousine. Pursued by the police, Arthur drives onto the grounds of a neighboring estate where he accidentally submerges the car in an artificial lake. Arthur escapes and begs Cynthia Vivian, the daughter of the house, for help. Cynthia instructs Arthur to impersonate James Valentine, a friend of her brother, gives him a change of clothes and introduces him to the party in progress at the estate. After the real Valentine appears, the two lock him in the garage. When the police arrive in pursuit, Arthur successfully evades them. While at the party, Arthur discovers the man who framed him and with Cynthia's help, clears himself and sends the guilty party to jail. Finally, Cynthia and Arthur, bound together by their adversities, realize that they have fallen in love.
