Since part of the first outlet works it is probably daisy chained to the others. With the power off remove this outlet and look for broken or loose connections. Since 1/2 of the outlet is working one of the metal tabs on the side of the outlet may have failed check this outlet first. a loose connection in a back stab or broken wire is very common for this type of failure. Depending on where the feed to the outlet is landed the bottom could work or the top if one of the tabs broke or failed under load (rare but with these symptoms probable).
