عادَتِ المَدرَسةُ مِن جَديد.
متين، الكتكوت، أَصبَحَ ضَخْماً وَمُخيفاً وَقَرَّرَ أَنْ يَصيرَ زَعيمَ الصَّفِّ.
يُحاوِلُ سامي، بِمُساعَدَةٍ مِن تيم وياسمينة، مَعرِفةَ السِّرِّ السِّحرِيِّ لِنُمُوِّ متين. وَلَكِنَّ تيم، كَعادَتِهِ، يَتَلقّى هُوَ العِقابَ مِن أَبيه بِسَببِ تَصَرُّفاتِ سامي البلْهاء.كَيفَ سَيتَمَكَّنُ تيم وَسامي مِن وَضعِ حَدٍّ لِتَصَرُّفاتِ متين وَعِصابَتِه؟
