A jealous suitor steals the groom's tuxedo and hires a pickpocket to strike the wedding and reception.

The pickpocket, a master of disguise but a dope as well, wears the tuxedo to the reception and steals all the gifts.

The suitor tells Mary that the groom has left her for another woman.

In the meantime, the groom has managed to be released from jail and sent back by the suitor.

When Mary learns her groom has not been unfaithful, she decides she wants to live, but as her hired killer is in disguise, she must wear a disguise herself (a man's suit).
