Exhibit 24

                                POWER OF ATTORNEY

        I, W. Alexander Holmes, do hereby appoint Francis Aaron Henry and Paul
N. Beck, as my true and lawful attorneys-in-fact (each an "Attorney-in-Fact"
and, collectively, the "Attorneys-in-Fact"), each, individually or jointly, with
full power of substitution and resubstitution, to have full power and authority
to act in my name, place and stead and on my behalf to:

        1)      execute and deliver for and on behalf of me, in my capacity as
                one or more of an officer, director, or significant stockholder
                of MoneyGram International, Inc. or any of its subsidiaries
                (collectively, the "Company"), reports, schedules, or other
                filings with respect to the reporting of ownership of or
                transactions in securities of the Company required to be made
                under the Securities Exchange Act of 1934, as amended (the
                "Exchange Act") or the Securities Act of 1933, as amended (the
                "Securities Act"), and the rules thereunder, including without
                limitation, Schedules 13D and 13G, Forms 3, 4 and 5 and Form 144
                and any amendments, corrections, supplements or other changes
                thereto;

        2)      do and perform any and all acts for and on behalf of me that
                such Attorney-in-Fact (in his or her sole discretion) determines
                may be necessary or desirable to complete and execute any such
                reports, schedules or other filings and timely file same with
                the U.S. Securities and Exchange Commission and any stock
                exchange or other authority; and

        3)      take any other action of any type whatsoever in connection with
                the foregoing which, in the sole opinion of such
                Attorney-in-Fact, may be of benefit to, in the best interest of,
                or legally required by me, it being understood that the
                documents executed by such Attorney-in-Fact on behalf of me
                pursuant to this Power of Attorney shall be in such form and
                shall contain such terms and conditions as such Attorney-in-Fact
                may approve in his or her sole discretion.

        I hereby ratify and confirm all that the Attorneys-in-Fact shall
lawfully do or cause to be done by virtue of this Power of Attorney and the
rights and powers herein granted. I acknowledge that the Attorneys-in-Fact, in
serving in such capacity at my request, are not assuming, nor is the Company
assuming, (i) any of my responsibilities to comply with the requirements of the
Exchange Act or the Securities Act or any liability for my failure to comply
with such requirements, or (ii) any obligation or liability I incur for profit
disgorgement under Section 16(b) of the Exchange Act. I further acknowledge that
this Power of Attorney does not relieve me from responsibility for compliance
with my obligations under the Exchange Act or the Securities Act.

        This Power of Attorney shall remain in full force and effect until I am
no longer subject to Sections 13 and 16 of the Exchange Act and Rule 144 of the
Securities Act with respect to my holdings of and transactions in securities
issued by the Company, unless earlier revoked by me in a signed writing
delivered to the Attorneys-in-Fact.

        IN WITNESS WHEREOF, I have executed this Power of Attorney as of
February 16, 2016.
