Those Interns are causing trouble again! Frustrated that the Residents are too busy dealing with their own drama to actually teach them, the Interns have started practicing on the only subjects they have available -- each other! But Sadie, that brazen, British troublemaker, takes things too far when she comes up with the idea of removing each other’s appendices and even starts cutting herself open to get started! Lexie and the other Interns do their best to operate, but they quickly lose control of the situation as complications arise. Now things have gone from a crazy elective surgery to a matter of life and death.
