Ada was firstly being captured and cuffed by a bad guy then she tried to release by herself but sure it is impossible. Afterward she was put on a collar, link up her neck and hands cuffed behind her, with hanged up from neck. She was suffered but found a handcuff key on the ground, so she picked the key up by foot then tried to unlock the handcuff, unfortunately it was discovered by the bad guy so he added a cuff on her foots.
