After a particularly aggravating day at school Frank rushes home to get ready for Linda who is supposed to be coming over. In his hurry to get home, Frank crashes his bike right into a huge anthill, and arrives home covered in angry ants. His mum rubs him down with vinegar to get rid of all the ants, ruining his chances with Linda and leaving him stinking of vinegar where ever he goes. Desperate for revenge against the ants he gets Thomas and Eric to help him. Their attempts fail and when Jerry appears and pleads for the ants' lives, the three friends follow him home to check out his ant collection. The ant jar falls and breaks and the ants run loose in Jerry's house. When Jerry's mum sees what has happened, she faints and is taken away in an ambulance.
