False Cheque Bounce Accusation

My mother is 71 years old. Widow. From Mumbai. She borrowed ₹50,000 from a money lender Lady in 2019. Not for herself but For a couple who needed it urgently. In return, my mother had to keep 2 blank and signed cheques as collateral/security with the money lender lady. After making some payment, the couple disappeared during lockdown. My mother continued making some more payment but due to lockdown and no income, couldn't. Total amount pending= ₹17000. She informed the money lender lady that she would resume payment later but this year in February, my mother got an SMS from the bank that a cheque had been deposited in her account for withdrawal in the name of Mr. XYZ (amount ₹2.5 lakhs) and due to lack of funds, the cheque had bounced. Cheque bounce charges were deducted from my mother's account. It seems that the money lender lady gave the cheque to some random person/man in Uttar Pradesh for extorting money from my mother. Now the random person has filed a case against my mother in a small town in Uttar Pradesh that he used to be in a business with my mother and had given her ₹2.5 lakhs cash as loan during my mother's needy days during lockdown. After giving the loan, the guy apparently went back to his home town in Uttar Pradesh and then asked for his money in return and my mother issued a cheque in his name, which duly bounced. Now, This story is completely fictional. My mother is a medical patient who can barely walk and is barely educated. She has never borrowed ₹2.5 lakhs from anyone. Doesn't know this Mr. XYZ guy and hasn't been in any business with him. The next summon date in on 14th August. What options do we have? I am okay going on her behalf as she can't even walk but I am confused with the legal options I have. Some people are asking me to fight the case from the town where the case was filed while some other people are asking me to approach Allahabad High Court to get the case quashed before 14th August. We are poor people from Mumbai and Mumbai is far away from the small town in Uttar Pradesh where the case has been filed or even Allahabad and going to those places every now and then is impossible financially. Any legal advice would be very helful.
