On Friday at school, Rachel is in trouble for accidentally causing another student to hurt herself. Rachel is often in trouble- she finds it difficult to follow her mother's advice to 'stop, think and do the right thing'. After school, Rachel, along with her parents and younger brother Tim, visits her older brother's farm. Rachel loves being on Roger's farm and loves looking for reptiles (which in Australia can be poisonous). Rachel goes looking for reptiles but when younger brother Tim gets too hot he decides to go back, then it happens! Rachel hears Tim call and he is holding a copperhead, a dangerous snake and then the snake bites him. That is when the danger really starts, how will Rachel save her brother and dare she face the wrath of the grown ups!
