         Re:      Registration Statement on Form S-8

Gentlemen:

         We have acted as counsel to FIRSTPLUS  Financial Group,  Inc., a Nevada
corporation  (the  "Corporation"),  in connection  with the  preparation  of the
Registration  Statement on Form S-8 (the  "Registration  Statement") to be filed
with the  Securities  and  Exchange  Commission  on August 21,  1998,  under the
Securities Act of 1933, as amended (the "Securities Act"), relating to 2,710,500
shares  of  the  $.01  par  value  common  stock  (the  "Common  Stock")  of the
Corporation  that may be offered  through  the Amended  and  Restated  FIRSTPLUS
Financial  Group,  Inc. 1998 Long- Term Incentive Plan (the "Plan"),  restricted
stock  grants to Jack  Roubinek  (the  "Grants"),  and  individual  stock option
agreements  listed on the cover page of the Registration  Statement (the "Option
Agreements").

         You have  requested  the  opinion of this firm with  respect to certain
legal  aspects  of the  proposed  offering.  In  connection  therewith,  we have
examined and relied upon the original, or copies identified to our satisfaction,
of (1) the  Articles  of  Incorporation  and the Bylaws of the  Corporation,  as
amended; (2) minutes and records of the corporate proceedings of the Corporation
with respect to the  establishment  of the Plan,  the  reservation  of 2,710,500
shares of Common  Stock to be issued  under the Plan,  the Grants and the Option
Agreements,  and to which the Registration  Statement  relates,  the issuance of
shares  of  Common  Stock  pursuant  to the  Plan,  the  Grants  and the  Option
Agreements,  and related matters;  (3) the  Registration  Statement and exhibits
thereto,  including the Plan, the Grants and the Option Agreements; and (4) such
other documents and  instruments as we have deemed  necessary for the expression
of the opinions herein contained. In making the foregoing examinations,  we have
assumed the genuineness of all signatures and the  authenticity of all documents
submitted to us as originals,  and the  conformity to original  documents of all
documents  submitted  to us as certified or  photostatic  copies.  As to various
questions of fact  material to this  opinion,  and as to the content and form of
the Certificate of Incorporation,  the Bylaws, minutes, records, resolutions and
other documents or writings of the Corporation, we have relied, to the extent we
deem reasonably appropriate, upon representations or certificates of officers or
directors of the Corporation and upon documents, records and





instruments  furnished to us by the Corporation,  without  independent  check or
verification of their accuracy.

         Based upon our examination and  consideration  of, and reliance on, the
documents and other matters described above, and assuming that: (i) shares to be
sold in the future  through the Plan,  the Grants and the Option  Agreements are
all in  accordance  with the  terms  of the  Plan,  the  Grants  and the  Option
Agreements,  (ii) the shares of Common Stock to be issued in the future are duly
issued in  accordance  with the terms of the Plan,  the  Grants  and the  Option
Agreements, (iii) the Corporation maintains an adequate number of authorized but
unissued shares and/or treasury shares of Common Stock available for issuance to
those persons who purchase  shares  through the Plan,  the Grants and the Option
Agreements,  and (iv) the  consideration  for  shares  of  Common  Stock  issued
pursuant to the Plan, the Grants and the Option  Agreements is actually received
by the Corporation as provided in the Plan, the Grants and the Option Agreements
and exceeds the par value of such  shares,  then we are of the opinion  that the
shares of Common  Stock  issued in  accordance  with the terms of the Plan,  the
Grants and the Option  Agreements,  or sold through and in  accordance  with the
terms of the  Plan,  the  Grants  and the  Option  Agreements,  will be duly and
validly issued, fully paid and nonassessable.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration  Statement and to references to our firm included in or made a part
of the Registration  Statement.  In giving this consent, we do not admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities  Act or the Rules and  Regulations of the Securities and Exchange
Commission thereunder.

                                                     Very truly yours,

                                                     JENKENS & GILCHRIST,
                                                     a Professional Corporation
